It is very unlikely that your (plain NTSC) TV is actually syncing to a 
800x600 signal. Even though you may have specified 800x600 modeline, the 
graphics card is doing the scan conversion to standard NTSC before 
outputting anything via TV-out. This is actually a major source of 
quality problems with the graphics card TV-out.
