I noticed the same problem. On fast movement it looks like the frame rate is less than normal. They looked good if there wasn't movement in the picture. I would guess that they haven't got the bugs out of the MPEG-4 encoding yet. I didn't get a chance to check Fox-4, since it the only DFW network channel that transmits in 720p, it may not have the same problem. I will keep watching the OTA channels, but the sat. HD locals could be useful for recording multiple network programs at the same time on the 622.
