Just to drop my two cents in (and that's a stretch since I haven't even 
installed my xbox front end yet).  If you're trying to keep the 4:3 ratio, 
I'd assume you'd need to specify your 6.0 and 6.0 to the same ratio.  I 
don't know the order of the parms, but would 8.0 and 6.0 make more sense?  
Again, I'm just guessing and am trying to help a little...
