I have to disagree with you Jeff. I use a VP30 to clean up all my video feeds and it can work wonders. Although it is true that for native HD sources (xbox 360, PS3, HD-DVD, HDTV programming) the DVDO doesn't have much to do, the quality it adds to 480i viewing is tremendous. Especially for our Directv SD signal the difference is night and day.

The other thing that these scalers does that never gets mentioned is that it takes the entire video input signal and scales it to your TV's native resolution. So even if your DVD player or satellite box scales the signal to 72op or 1080i, it also commonly adds a good 5-10% of overscan to the image. The DVDO box reclaims that extra area and passes the entire picture to your TV set.

We love ours, I wouldn't do without it. With used VP30s going for ~$1000, it's not such a huge bite for the quality gained.
