Hi Don, I'm presently using a CI scaler, and the adage, garbage in, garbage out is apropo. I've found that, if the DSS signal is poor, no amount of tweaking can make the picture much better. Although the PQ is better using the CI with DSS, the PQ on a PPV sat signal is far superior. There seems to be far less compression artifacts on PPV channels, and what few there are, the CI handles quite nicely.
DVD is a totally engaging experience with the CI. It works like a charm, is much easier to use than HTPC, and with no crashing, as has been reported many times on this forum about HTPC's.
Cheers, VB
