I want to make a DVD out of .avi's i already have. I have never burned a dvd before so i started searching. I found a copy of neoDVDplus5. It looks like it is doing what it's supposed too, but it is decompressing the files from 300-320MB to almost 4GB's. Is this normal? I thought of double layer dvd's but i don't think i have a double layer burner. Any advice, knowledge, or instructions you have would be greatly appreciated.
