Alas, the ATTC web site (like the ATTC) is no more.  It used to have 
posted the results of testing it performed on behalf of ATSC T3/S6 to 
see whether any existing ATSC receivers could not deal with 720 x 480. 
 They tried various modes (4:3 and 16:9, different frame rates).  Of 
seven receivers tested, one was unable to properly deal with 720 x 480 
in one mode, and another was unable to do it in a different mode.  So, 
yes, there's a problem.

As a T3/S6 member at the time, I'm not permitted to say what the group 
did on the presentation of the data, but the ATTC report was public.

TTFN,
Mark
