Is linux way more picky about reading dvd's than windows?

I've got two linux boxes here. Both are modern machines with brand new Benq DW1640 drives in em. One is running Fedora 4 and the other Ubuntu 5.10. I'm trying to copy a bunch of dvd's (not encrypted).

On both boxes I'm getting multiple read errors on many of the disks and can't finish. I've tried K3b as well as just copying the ts_video dir in nautilus. Makes no difference which way I do it.

I then walk the same disks over to any of the three windoze-xp boxes here and they copy fine. No problems at all.

What's up with that???

The only suggestion, may be you have wrong driver? It is possible your dvd-drive is not supported well by Linux.

Well maybe, but not all disks are failing. I was able to make copies of probably 25% of them with no problems. Wouldn't a bad driver affect all equally?

When I had problems of the same character (except I did not know how does my drive work in Win32) I bought a new one. Now I am happy with it
In my case I was able to read almost all discs, but sometime (SOMETIME) some (SOME) discs were refused by my drive! I knew which discs better on reading and which worse, but they could be readed SOMETIME. I was annoyed by that for time until I bought a new drive.

The Benq DW-1640's are pretty highly rated drives. I read a lot of reviews and user comments before buying. Just about everybody raves about how good they are.

The DVD's I'm copying seem pretty badly burned. I'd guess the guy that made them burned at max speed on cheap Maxell blanks. In the end, out of 25 disks I was able to copy probably around half of them with the linux boxes. The rest had to be done on the windoze machines.

Four disks couldn't be read on any machine in any of the four lower cost drives (2-Benq, 1-LG, 1-Lite-On). Bad CRC errors. So I cranked up #2 (Big Blue) and copied those with the Plextor PX-716A. Damn, I love that drive! It didn't even blip - just chugged thru em.

Don't forget also that some movies and such are highly compressed just to make them fit on a DVD... in addition to being ( snicker...) "encrypted." Commercial video DVDs are likely to have these things, vs. home-made ones. You gotta take these things into account.

It's the difference between what you can do with iDVD versus DVD Studio (on a Mac)...
