hello
I have two DVDs which contains AVI files. I can't read it in my fedora box but it works in gentoo and windows.
I used the DVD drive and the DVDs before so I don't think it is a HW problem.
I got this in dmesg: [ 7892.555826] sr 1:0:0:0: [sr0] Unhandled sense code [ 7892.555834] sr 1:0:0:0: [sr0] [ 7892.555836] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 7892.555839] sr 1:0:0:0: [sr0] [ 7892.555842] Sense Key : Medium Error [current] [ 7892.555847] sr 1:0:0:0: [sr0] [ 7892.555851] ASC=0x10 <<vendor>> ASCQ=0x90 [ 7892.555854] sr 1:0:0:0: [sr0] CDB: [ 7892.555856] Read(10): 28 00 00 00 00 00 00 00 02 00 [ 7892.555866] end_request: I/O error, dev sr0, sector 0 [ 7892.555872] Buffer I/O error on device sr0, logical block 0

Clean the disc, or clean the drive? Sometimes cleaning a drive improves things with some discs, when the drive is apparently working fault free with other discs (they're probably more readable). If it's a laptop drive, where the laser mechanism is accessible, careful hand cleaning is better than one of those discs with a brush glued to it (they bash into the lens).
Or you could have some particular discs that are bordering on the edge of being readable, that work sometimes, but other machines are less forgiving.
Some disc and drive combinations are not too compatible, though I haven't heard that kind of complaint for a while. I always use the best discs that I can get, because I hated having to deal with that problem. Some people just use the cheapest.

George Orwell's '1984' was supposed to be a warning against tyranny, not a set of instructions for supposedly democratic governments.
hello
well, I've tested the DVDs on a Windows 7 and in a Gentoo box. They work fine. I've tested the DVD drive with different DVD discs and it works, so I've opened a low important bug ticket in bugzilla. I don't think it will fix :(

OK... But, did you move the DVD drive into a Win7 or Gentoo Box and try with those DVDs?

Those errors generally indicate that the disc(s) are dirty, as it is a "medium error" (meaning the DVD media, not the size between "small" and "large").
Try cleaning the DVD. I use eyeglass cleaner solution and the cloth that comes with it. Remember to wipe from the center of the disk to the edge in a radial motion (straight line) and don't apply a lot of pressure. Do NOT wipe in a circle around the disk...any scratches you get doing that can confuse the tracking mechanism (CDs and DVDs are written as a spiral track starting from the center of the disc outwards like an old vinyl record in reverse).
A blast of air into the drive (be careful!) can be helpful as well. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@alldigital.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Real Time, adj.: Here and now, as opposed to fake time, which only - - occurs there and then - ----------------------------------------------------------------------
