Yes, this problem occurs with xine from the command
prompt, so I, too, am thinking video driver and/or

It could be cooling. Would the video stop, yet the GUI
still be active if it is a cooling problem? In both
xine and myth, I get kicked out to the x-windows GUI,
where I can open windows, etc. I have this in an antec
overture case, which I am not very happy with. I can't
add fans. I am thinking about pulling a tuner card and
getting more room around the video card.

Here is my xorg.conf:

# RgbPath is the location of the RGB database.  Note,
this is the name of the 
# file minus the extension (like ".txt" or ".db"). 
There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are
concatenated together)
# By default, Red Hat 6.0 and later now use a font
server independent of
# the X server to render fonts.

# If you have a US Microsoft Natural keyboard, you can

# If you'd like to switch the positions of your
capslock and
