Why would you want this?  Is there a screen shot somewhere showing why
this is useful?  I'm just curious...

Now what I'd like to see is an easy minor zoon that compromises showing 4:3 
material on 16:9 sets.  Perhaps you could split the difference between what 
you would cut off to keep the aspect ratio correct, but reduce the size of 
the black bars by half.  Then again, I'm not sure if I'd use the feature that 
much, until I had it.  For some odd reason if I zoom much beyond the normal 
fit of 4:3 on the screen now, it tends to corrupt things.  Sometimes you 
might want to do that do that to fit 16:9 source material that is showing on 
a 4:3 channel on a 16:9 screen.  I've never looked into the issue, but I 
suspect it might be video card (ati) related.
