[FFmpeg-user] corrupted media?

I recently got a commercial DVD of a movie and right while placing it
in the caddy it (sometimes) apparently gave me reading errors
$ Advanced probing on /dev/sr0 failed while reading block size
Disc in /dev/sr0 is a Video DVD
but sometimes it doesn't
$ Disc in /dev/sr0 is a Video DVD
Disc in /dev/sr0 is a Video DVD
Then if you try to play it using mplayer it gives you lots of mostly
"frame CRC" and "mismatch sync" errors
It seems to be a movie using a very old DVD format ([1984] "Once Upon
a Time in America"), but it seems to be physically OK (no
outward/obvious signs of wear at all) and the owner claims it was
played just a few times. I also tried using VLC to no avail.
Is there a way to watch that movie using mplayer?
thanks
