dvd disk plays ok, but ripped iso does not - why?

[qazplm]

Hi, years I converted lots of old home videos to dvd - and I can play the dvds ok (both in player and in pc dvd drive)

But now I want to have those DVDs on my PC.

I've tried DVDfabExpress, DVDshrink and DVD decrypter.

I get the same problem with each - when I view the resulting files on my hard drive they're full of BAD pauses, skips, jumps, sound problems which do not show up at all when I shove the DVD in the drive and view it directly.

I guess that these are the results of real errors on the DVD but that the dvd viewing software which reads from the drive does some sort of compensation which makes it viewable, but that the ripping programs dont do this.

What can I do to rip a viewable ISO? Do I really have to record my DVDs back to video cassette, then record a new DVD from there?? Or is there ripping software out there which will do the same thing my dvd drive does when I use it to view the DVDs?

Thanks for any help

Hi!when I view the resulting files on my hard drive they're full of BAD pauses, skips, jumps, sound problems which do not show up at all when I shove the DVD in the drive and view it directly.What software DVD player are you using to play the hard drive versions?

Try defragmenting your hard drive...

Hi, the software for playing back definitely isnt the problem, because I have no problems with other ISOs, just ones ripped from certain home DVDs.
I've tried windows media player, power dvd.. and also tried editing in video redo. The ISOs are full of errors in all.

Is there any ISO ripping tool which emulates what happens when I view a dvd directly from the drive? I dont care if it rips the ISO in real time.

By view, do you mean loading them into Daemon Tools/Alcohol and loading from the virtual DVD drive like you would the real drive? Or is it an iso reader in some software? Some driver issue might cause the former to stutter, a bad implementation the latter.
