I'm not disputing this. Actually, I can't. No HDTV experience (No  
HDTV owned). I'm just clarifying the point made above where Steven  
Adeff says he can go from 1080i to 720p without problems. I'm just  
pointing out that we're not talking about 1080i->720p, but 1080i- 
 >1080p. At least, I think that's what we're trying to do.
