Update.
Samsung DLP and today using the DVI. 720P
When I first got VOOM I could not watch the SD channels using DVI because of black bars at the top and bottom. Since I changed back to DVI today, SD is perfect and fills screen. Picture seems better than before and significantly better than it was on than it was a year ago.
Regarding the input. Not sure if it looks getter leaving the VOOM box at 1080i and letting the TV do the conversion or having the VOOM box do the conversion before passing on to the TV.
