Errors ripping with DVD Burner but not DVD Reader!

[sgf323]

I have 2 DVD Burners. One is an HP 200i and the other is an NEC 3500. The 3500 does better than the HP at ripping but still they both sometimes give errors when trying to rip a disc using any of DVD Decryptor, DVD Shrink, DVD xCopy Express. The error usually is Cyclic Redundancy check from Shrink and a read error (don't remember exactly) from Decryptor.

I also have 2 CDRW/DVD Combo drives (one in the laptop and one IDE) and they have NO problem at all ripping the discs that the burners can't rip! What is the deal? Are burners more picky about the quality of the discs they read or are my regular DVD drives not susceptible to some forms of protection that may be on some discs?

I have a CDR/DVD ROM combo that rips very well but is a noisey bastard so I use my DVD Burner. Both rip with no errors at all.

In my experience, different readers are indeed very different when it comes to what they read and not. I think you'll find differences between makes and models as well as between individuals of the same make/model. I have a DVD reader that is better than my writer at reading DVD, but needs perfect CD to read at all, while my burner reads almost any CD I try, but has truoble reading some DVDs that my reader has no problem with.
