I occassionally see combing artifacts on some Dish SD channels using my 722 receiver. They'll randomly be there during a slow pan typically, but paradoxically not during faster pans (even in the same show). I've never seen this on any of DISH's HD channels, nor on any DVD's or HDDVD's (played back on my Toshiba A2 set for 1080i output). And the combing pattern has fairly wide "teeth" - not narrow ones as you'd expect at 1080 resolution.
You'd normally expect deinterlacing artifacts to be a function of the TV, but this just doesn't seem to fit with what I'm seeing (the randomness, the wider teeth). It would almost guess that they're in the signal itself somehow. I can't remember which specific channels I've seen it on. I just noticed it on SciFi - watching an SD episode of X-Files.
I'm using a 722 hooked up via HDMI to a new Mitsubishi 65" DLP (model WD-C657, very similar to a WD-65733 or WD-65734).
