The dvdnav-Patch is able to play this sort of discs, at least at my batch of problem discs. It seems to use some altogether different read mechanism to steer around the sectors. So ATM I can finally play all my DVDs again (subtitle problem(s) solved, Copy Protection playback solved)
Thanks for this piece of info, Alexander. I didn't know about dvdnav before. Unfortunately, recompiling mplayer with dvdnav support and playing this disk with "mplayer dvdnav://1" made no visible difference. The playback is still choppy. By choppy I mean that the image freezes for about a second and then catches up. This happens every 5-10 seconds.
Any other ideas on what I can try to diagnose this problem?
Thanks.
If this happens, it might be the DVD drive is not up to the task on delivering the data fast enough. Either the drive lacks DMA-support (nowadays quite unlikely though) or the drive is slowly reaching it's end of life span (I already had to sort out 3 DVD drives in the last 4 years, the first one clearly had problems reading some DVDs, especially those with a slightly golden surface (as the Godfather DVDs from Paramount had, better with the silver surface often encountered with DVDs from Warner, though. I didn't have *that* much DVDs back then (now I'm at about 400). If there's some error reading the disc and the drive has to re-read, you can catch a glimpse at it with the `dmesg`-Command, which outputs read errors occured on the DVD drive. (though it's saturday, in canada there's still the entire day to get a new DVD drive... :) hth, Alex
