pc? I have a pretty average, older dvd burner "2 years old"when I burn files, any files, either cd or dvd, it sometimes only work on my reader, instead of other, newer computers. I've tried and confirmed this on 3 different pcs, with different brands of cds. If my burner sucks, then why read perfectly on it and not other, better ones?these are good answers, thanks everyone. Here's one scenario in particular. The other pc is new, with a lp dvd burner. It has the same version of Nero as mine. I tried it twice, first time it was a cdrw with pictures, burnt as a data disk. Some folders froze on it. Second time it was a data dvd with multiple avis. 2 of which froze at the same place when playing.My main concern is that I backup many files on dvd. But what if my new system won't read them.
