Error recovery

Although I have no problems with ID4, on X-Menu I often have the video 
window die.  The program stays open, and I can click 'disc' and 
fast-forward to the approximate location I was just at and keep 
playing, but its quite irritating because it happens sometimes after 30 
seconds, sometimes after 5 minutes, but always in the same spots.

The player gives:
vpar info: stream periodicity changed from P[3] to P[2]
vpar info: stream periodicity changed from P[2] to P[4]
vpar info: stream periodicity changed from P[4] to P[1]
vpar info: stream periodicity changed from P[1] to P[3]
dvd error: can't find next cell
input: EOF reached
module: unlocking module `idctmmxext'
module: unlocking module `motionmmxext'
ac3dec warning: error during audioblock
aout info: fifo #0 destroyed
etc.

The Linux (2.2.12) kernel has quite a few IO errors reading the disc at 
these points as well, although not all the errors cause this problem;

Oct 21 19:10:02 mbabcock kernel:  I/O error: dev 0b:01, sector 5000 
Oct 21 19:10:02 mbabcock kernel:  I/O error: dev 0b:01, sector 5252 
Oct 21 19:10:05 mbabcock kernel:  I/O error: dev 0b:01, sector 4744 
Oct 21 19:10:06 mbabcock kernel:  I/O error: dev 0b:01, sector 4996 
Oct 21 19:10:06 mbabcock kernel:  I/O error: dev 0b:01, sector 5000 
Oct 21 19:10:06 mbabcock kernel:  I/O error: dev 0b:01, sector 5252 

These are from this disc, but when I reproduced the last cut-out, these 
didn't appear.

Is there any way that this EOF condition is being incorrectly reached?
What other debugging could I do?
