Anybody using a DVD scaler?

I don't have one. But I've heard the DVDO stuff is generally pretty good for the money. Most people who have it have or plan to have SDI mods I would assume.

I'm using a Iscan HD processor between my source and
front projector. Since my DVD player offers only a 480i
signal, it made a significant improvement. Even when I
plugged in my progressive player, the signal was cleaner
and sharper via the Iscan processor. THEY WORK, do they
improve by a factor of 40 to 50% as indicated by upscaling
to a 720 resolution, I say no. However, I can comfortably
suggest a 10 to 15% overall improvement.
As Howie said, mine came with a SDI card, of which I'm
currently not using. Seems more of a future modification that I will play with once I buy a SDI source.

Good Luck

Would the purchase of an HD upscaling DVD player like the Denon 1910 (or other competing models) solve the problem for cheap? It's only $250 list and does 720P as well as 1080i. This would negate the need for an extra box and cables.
