    Okay guys, simple question here.

    I'm trying to enable my PSP system to download movies from DVDs onto its hard drive. I do not yet have all the hardware. One of the pieces I'm missing from this project is a larger memory stick for the PSP to have data space to download to. (A DVD ROM is also in the works) How much space would I need on the memory stick to be saving movies?

    That all depends on the movie, it can be as small as 3.5 GB or as large as 8.5 GB.

    Umm you don't need memory to store movies you need hard drive space.
    Ditto what "SS" said.

    The size depends on what is on the DVD, nowadays they pack tons of extras such as out-takes, interviews, trailers as well as audio and captions in several languages. If the running time of the movie is under two hours they can put it all on one DVD, if it is a longer movie they put the extras on a second DVD. Either way they do it you still rip the DVD to your hard drive and in some cases defeat the copy protection.

    The PSP uses a memory stick (similar to digital cameras) AS a hard drive.

    3.5 gigs for a short movie? Dang! Even the 2 gig cards are $119 over here.

    Is there any way to make this work?

    What are you trying to do? PS2 seems like a long way around to be backing up DVDs. Your PC is a far better choice for a lot of reasons.

    In America is not really worth copying DVD movies.In countries where DVD movies are much more expensive it might be worth all the trouble and expensive but it's still just a MOVIE !!!How many times are you going to watch the same movie?The main public library here in DC has a suscrpition for all the latest DVD movies and I can sign up to check them out for free.Only I cant choose the day.I have to take it when it's available.Even renting DVD's better then buying and storing DVD's I might watch once or twice.Even buying DVD in America isn't very expensive anymore but then you have to keep them somewhere.If you really want a home collection it's cheapest and easiest to replace any that become damaged or lost as needed then trying to copy them.

    First of all, I have a PSP, NOT a PS2. PSP's are designed to do many things besides just play games. They also play movies using a proprietary DVD or things you have downloaded from your computer. They can play MP3 files and also store digital images from your digital camera.

    It seems silly to me to be buying these DVD movies that can only be played on the PSP (Standard DVD players can't play them-they don't fit). Rather than do that, I thought I would dispense with buying them altogether, and when I want to watch a movie on it, instead download it from my computer (after ripping it from the DVD) to the PSP's memory card. Presto, the memory card performs the same function the PSP DVD would have done, except that now I don't have these wierd DVD's hanging around, and I can watch any movie from my DVD collection on the PSP. I would then effectively have a portable, battery operated DVD player.

    I have the software to do it, in theory, but what I'm not sure about is whether this is feasible without overwhelming the memory card. 3.5 gigs for a small movie is a lot of data. I was kind of hoping the file would be smaller. On the other hand, I have noticed that with the PSP and proprietary DVD's, unlike a standard DVD player, there is no provision for a zoom command, leading me to wonder if this might be because the video resolution is optimized for the PSP's 2x3 inch screen with no provision for zoom in order to shrink the file size to something smaller. After all, the DVD's it plays are physically smaller than a standard one, and there is no need in making them to worry about making them look good on a big screen TV. Is my thought process making sense here, or am I trying to do the impossible?

    Just because something can play DVD's doesn't always make it good choice to use it for that.As stated earlier many DVD movie are larger than 8.0GB's.I'm not sure how well you can enjoy watching a movie on a 2x3 inch screen.It sounds like for what it will cost you just in hardware you could buy a cheap portable DVD player.Even with a large enough drive/memory you wouls still need to spend a lot of time copying the movies.

    OK, I gotcha now...

    You can reduce DVDs to all sorts of small sizes, with a loss in quality of course (just like the loss you have whan you use those oddball Sony PSP disks). With some work you can jam a DVD onto a CD. It'd look OK on the PSP, but as for playing it on a TV somewhere... prolly look like crap.

    First question... what formats can the PSP handle? I doubt it can mount a DVD image you have on a Memory Stick. If it can't, you'd have to extract the base video file into a file format the PSP understands.

    Problem is, to make an .mpg or .avi or other "standard" file from a DVD you need to do manipulations to break the CSS encryption that are technically illegal. Software to do it is readily available, but you'll have to go find it yourself, linking to it is a violation of GT's ToS (for that matter, mentioning it might be, but I'll give it a shot).

    Providing that you don't go around selling copies that you made this way, but only use the converted files for personal use, if the DVD the file is based on was a legal copy, why would anything done to fool with the encryption in order to play it on another format be illegal? (Think 1980's here--copying music from record to cassette tape so you could play it on your car stereo)

    Copying the file is not neccessarily illegal.

    Breaking the encryption is.

    Digital Millenium Copyright Act (DMCA)

    Chapter 12

    Paragraph 1201 Circumvention of copyright protection systems
    ‘‘(2) No person shall manufacture, import, offer to the public,
    provide, or otherwise traffic in any technology, product, service,
    device, component, or part thereof, that-
    ‘‘(A) is primarily designed or produced for the purpose
    of circumventing a technological measure that effectively controls
    access to a work protected under this title;
    ‘‘(B) has only limited commercially significant purpose or
    use other than to circumvent a technological measure that
    effectively controls access to a work protected under this title;
    or
    ‘‘(C) is marketed by that person or another acting in concert
    with that person with that person’s knowledge for use in circumventing
    a technological measure that effectively controls
    access to a work protected under this title.
    ‘‘(3) As used in this subsection-
    ‘‘(A) to ‘circumvent a technological measure’ means to
    descramble a scrambled work, to decrypt an encrypted work,
    or otherwise to avoid, bypass, remove, deactivate, or impair
    a technological measure, without the authority of the copyright
    owner; and
    ‘‘(B) a technological measure ‘effectively controls access to
    a work’ if the measure, in the ordinary course of its operation,
    requires the application of information, or a process or a treatment,
    with the authority of the copyright owner, to gain access
    to the work.

    The DMCA is a complete turd, and in courts for various reasons, but decrypting DVDs is technically a violation.

    There is a free program called DVD Shrink that can compress DVDs. I don't know how small it could make the ones you have, but it might be worth a try.

    Problem with DVD Shrink is you still have a DVD image when you're done. I don't think the PSP is smart enough to mount a DVD image that shows up on a Memory Stick. If you could find a way to burn the PSP format (UMD?), then you could do DVD Shrink to reduce size and use the burner to make PSP native discs.

    Almost, but not quite. UMD's media appears identical to a DVD (except in miniature) on visual inspection except that the "DVD" is mounted inside a small plastic case from which it is not intended to be removed. It compares to a standard DVD much as a 3.5 inch floppy disk compares to the 5.5 inch type floppy disk. If you could directly burn a UMD, you would the need to have a casing to put it in.

    The software I have advertises itself as capable of making the conversion to a file the PSP can use if supported by appropriate hardware (ie DVD ROM on computer). I guess the sticking point here is the question of how big a file will the DVD movie be when the program gets done doing it's thing (The program literature does not say). I guess I may need to buy the DVD ROM to find out. It's an upgrade I needed to do anyway, but it's too bad I apparantly have to do it before I can find out if the memory card can handle it.

    You can get DVD-ROM drives for about $25. A DVD-ROM/CD-RW combo for $30. Or a DVD-RW for $40 or so. DVD writer is a handy thing to have, and gives you more things to do than just rip DVDs...

    Now, if you have a way to fake out the PSP on a Memory Stick, then DVD Shrink can handle the size problem. Use it to make an image of the size you need. Use Daemon Tools to mount the image, then use this PSP tool you found to make the file you need from that image.

    Myself, I'd just capture the video stream from the PC's DVD into a file, reduce that to a VCD-sized format, then put two or three flicks on the flash memory.

    That seems pretty simple. The question is, what does the PSP like for compatibility? MP4? WMV? Quicktime?

    To begin with, please understand that I'm still learning, and actually know very little about this stuff. According to the PSP's manual, it says it plays "MP4 (video codecs for the video files that conform to the Memory Stick video file format are MPEG-4 or AVC)" Whatever that means.:dunno:
