I've run into this problem a number of times on my Linux systems. In a
couple of cases what where essentially scratched disks played on both
my HT DVD player as well as Windows but would not play in xine.

I talked with the xine guys and they said (at the time maybe 3-4 years
ago) that their error recovery wasn't nearly as good as they wanted it
to be. At that time xine was the best around.

A READ10 issue is potentially a firmware issue in the drive since it's
the drive's processor formatting up data to send over the cable. My
suggestion would be try it on every system you have there. Some drives
read around problems better or do better correction at the drive.
Maybe you can find a firmware upgrade for the specific drive. Not
specific to these READ10 errors but some folks using 1394 peripherals
have improved performance in this sort of situation.

HTH,
Mark
