Ultimately the goal is to get all TV broadcasting off of VHF channels  
- the government wants to auction off those frequencies, or perhaps  
give them to Haliburton :-)

During the transitional period there may be some ATSC on VHF, but it  
should be an uncommon situation.

I still think trying to use both sides of the HD-3000 isn't worth the  
effort, considering how cheap an NTSC frame-grabber is.
