Hmmm, you don't say what kind of capture card you have, but based on 
another posting (which you put in a new thread... please don't do 
that!) where you indicated you were using 'mplayer /dev/video0', I 
assume you have a PVR-250 or similar card?

Hmmm....

this *could* be an issue if you don't have a monitor connected when 
you're trying to display to the TV.  Try commenting out this line 
completely; the driver should correctly detect what's connected.

Also,

This *might* be problematic... try using 800x600, as most integrated 
TV-outs won't do 1024x768.

Beyond that, I don't have any suggestions.
