No joke.  Everyone talks about the resolution as the determining factor 
of video quality, but as any Myth user knows, the right resolution with 
the wrong bitrate is worse than a lower resolution at the same bitrate...

I'm also amazed at how poorly they encode some of the video--often 
commercials such as local spots or "on location" news segments.  In 
addition to compression artifacts, they have deinterlacing and scaling 
issues.  At least on those issues, I have hope they'll go away as the 
broadcasters gain experience and as technology hides the need for 
experience.  ;)  The bitrate issue, though, is not likely to get better 
(probably worse as broadcasters try to put more channels in the same 
bandwidth) unless the spec switches to a higher-compression format (but, 
considering that none of the HDTV sets purchased so far in the US have 
support for H.264 or whatever, I doubt the FCC will be doing that 
anytime soon).
