4x 8x 16x ... What does it mean necessarily? I make backups of all my DVD's and they tend to have skips or errors (actually I suspect it's the DVD player as well, it's old and hates backup copies of DVD's, rarely plays them). I am wondering if it is because I record them at such a fast speed. I burn the DVD at 16x and the actual blank dvd disc says 4x on it. Does that mean I should burn at 4x ? What does the 4x on the disc imply? The read speed? How does that relate to my dvd player?
