I believe the answer to that question was just posted to another thread:

Remember that Bob can only run if the display frame rate is 2x the source. 
i.e. if your TV is 60 hz, and the (deinterlaced) signal is 30 hz.  If the 
incoming picture is 60 hz (i.e. 720p) and your tv refreshes at 60 hz, bob 
can't do anything for you.

But if you 'unsquish' your display, and run it at say 1024x768 at 60 hz, 
that may open up a whole raft of possibilities.  (Going to be mostly 
dependent on what your TV will accept.)
