Hey Cory,

Many sets provide a nonlinear stretch mode for 4:3.  Just so people 
don't get confused, we're not talking about stretching a 4:3 to 16:9 
(which is, of course, supported by XV) it's a warped stretch where the 
middle 60-70% of the screen is zoomed by a fraction, and the remaining 
15-20% on each side is stretched the rest of the way.  It's a great 
compromise when viewing 4:3 on a 16:9 monitor.

Depending on your modeline, you can trick your HDTV set into doing it 
for you.  If you can change your output resolution to 4:3 480p then your 
TV should recognize this and let you stretch it.  Right now, my output 
resolution is 16:9 540p so my TV (Toshiba 51S500) only gives me 16:9 and 
16:9 zoom.  I'm willing to live with it.  I don't know of a way to 
toggle output resolutions on the fly.  If I could, then switching to a 
4:3 resolution on demand would be great.
