[MPlayer-users] [BUGREPORT] I/O errors on DVD playback (totem playsit fine)

[vitko <vitk0@xxxxxxxxx>]

Short story:

mplayer 1.0pre7 fails to play certain DVD, while totem plays it fine, see
attached mplayer and dmesg logs. (Debian Sid + Marillat's packages).

Long story:

Some time ago I met DVD which could not be backed up using vobcopy -m,
as it generated a lot of errors in style

   Buffer I/O error on device hdc, logical block 67446
   hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
   hdc: media error (bad sector): error=0x34 { AbortedCommand 
LastFailedSense=0x03 }
   ide: failed opcode was: unknown

My XP addicted friend confirmed even DVD Shrink(?) software fails to read the 
disk,
as it freezes in certain moment while drive is spinning indefinitely trying to
read.

Anyway I've been able to use mplayer -dumpstream to get contents of that DVD and
so save the day.

...

Tomorrow I got in my hands Million Dollar Baby (the movie, actually! :-), which
vobcopy failed to process, causing kernel to spit a lot of Buffer I/O error
messages. Worse was to come - mplayer dvd:// played minute or so, then kernel
started spitting

   ...
   Buffer I/O error on device hdc, logical block 67434
   hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
   hdc: media error (bad sector): error=0x34 { AbortedCommand 
LastFailedSense=0x03 }
   ide: failed opcode was: unknown
   end_request: I/O error, dev hdc, sector 539480
   hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
   hdc: media error (bad sector): error=0x34 { AbortedCommand 
LastFailedSense=0x03 }
   ide: failed opcode was: unknown
   end_request: I/O error, dev hdc, sector 539488

   Buffer I/O error on device hdc, logical block 67436

   ide: failed opcode was: unknown
   end_request: I/O error, dev hdc, sector 539496
   Buffer I/O error on device hdc, logical block 67437
   ...

As a blind test I fired up totem, which to my astonishment played the DVD with 
no
apparent problems at all! I even checked my drive with regionset, it is 
correctly
set to "2".

I'd be very glad to provide any help to debug this mysterious issue.
