playing DVD with an error makes players hang


Hi,

I have a DVD which I think has some errors on it. These errors are about half-way on the disk, which means I can view the first half normally.
When playing in either mplayer, xine or totem I get a error message and the player stops, which is expected. What is less expected is that when I try to restart it to skip over the faulty part, all the players keep hanging a long time, and even opening the dvd-tray is impossible. Rebooting solves the problem but I have to be careful to completely skip over the errors if I don't want to reboot again.

A typical example is mplayer not filling the cache and just stopping. Often, I can't even use Ctrl-C to kill it completely, it gives the message 'MPlayer interrupted by signal 2 in module: demux_open' but keeps hanging.

At this moment dmesg reports these errors:
Code:
Buffer I/O error on device hdd, logical block 1916912
hdd: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdd: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdd, sector 7667652
Buffer I/O error on device hdd, logical block 1916913
hdd: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdd: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdd, sector 7711760
Buffer I/O error on device hdd, logical block 1927940
hdd: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdd: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdd, sector 4618848
Buffer I/O error on device hdd, logical block 1154712
hdd: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdd: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
...
I understand that players can't read when there are errors, but is there anyway to not let them flip out until reboot when they read this bad sector?

Thanks you very much,
Jedyte

Edit: btw when this problem occurs, the read light of the drive stays on, and you can hear it spinning and stopping over and over.

Yes, killall usually works. I'm running Gnome.
