Hmmmm, never thought to check that before but it appears that it is at 50 Hz. I am outputting through S-Video to an NTSC set, I guess that I had assumed that it was running at 60 Hz. Any attempts to change it have been futile, xrandr fails and setting the mode to 1024x768_60 in xorg.conf fails. Am I mistaken in assuming that I should be outputting at 60 Hz for NTSC?

I will try this when I get a chance, compiling mplayer from source is not just something I can do on a whim

My current mplayer reports "MPlayer UNKNOWN-4.4.1", dpkg says it is "2:1.0-svn29964-0ubuntu3"

I get a few different errors, with a few different behaviors. The errors with debug enabled are:

VDPAU nvidia: Error detected 0 5916
VDPAU nvidia: Error detected 0 5009
VDPAU nvidia: Error detected 0 481

Different error behaviors:

1) Screen will blank for a moment, mplayer will usually recover, Myth will sometimes recover but X display is fine.

2) Screen will blank permanently, sometimes audio will continue in the background. Restarting X will restore display.

3) Display will go an all pinkish color (under 195.x) or pixels will randomly change color and move (under 180.x and 190.x). Restarting X will not fix this problem, the machine needs to be rebooted before X will work again.

I don't know if the behaviors listed are correlated with the specific errors but I suspect that they are. When the display errors I usually get NVRM errors in the syslog, here are some sample errors:

[ 170.652293] NVRM: Xid (0002:00): 6, PE0004 <-- Normal recoverable error???
[ 382.369619] NVRM: Xid (0002:00): 13, 0004 00000000 00008297 00001348 00146214 00000005
[ 533.740558] NVRM: Xid (0002:00): 13, 0004 00000000 0000502d 00000200 00146214 0000000c
[ 546.924525] NVRM: Xid (0002:00): 6, PE0004
[ 596.991798] NVRM: Xid (0002:00): 6, PE0004
[ 606.072152] NVRM: Xid (0002:00): 8, Channel 00000004 <-- I think the display dies with a #3 type error here
[ 619.072149] NVRM: Xid (0002:00): 8, Channel 00000001
[ 628.072153] NVRM: Xid (0002:00): 8, Channel 00000001
