Hi Steve,
I like the PVR abilities of the AccessDTV card, and swapped out the HiPix for it. Plus, I was very much of an early adopter on the HiPix (pre-ordered before release) and I had a bad stuttering issue that I couldn't resolve.
I understand that the technical hurdles have come down, so it's probably great today!
Have you seen Hi def on the D-ILA yet?
