    Using a 42" screen, you won't be able to see all 1920x1080 pixels 
further than about 4-5 feet away, but one reason I went to a 1080p set 
is that it is hard for computers to output a good interlaced signal.
I have a 61" Samsung DLP, and I find that mythDVD looks better than my 
standard DVD player hooked up via component.
I don't have an HD capture solution, so my mythtv watching is always SD 
from a PVR-250 capture card. It is definitly watchable from 8 feet away.

I used to have a 26" HDTV CRT set that could do 1080i from its HDMI 
input. I tried a few times to get my Geforce 5200 to output a proper 
1080 interlaced signal with no luck, so I just ran it at 720p.
Its also a lot harder to play games in interlaced mode. (PC or xbox360)
