The 720p channels (ESPN, ESPN2, ABC) were, oddly enough, 1280x720. No idea what the MPEG4 locals are doing.SD is, almost exclusively, 480x480, which sounds peculiar but actually is the same as the NTSC version of Super Video CD (SVCD).They also do bizarre things like flipping field dominance in a wacky bandwidth-saving scheme, etc. When I checked using my HR10-250, all of the 1080i channels were using 1280×1080.

I read the 1440x1080 somewhere. Do you know if they're using 1280x1080 on all channels, or does it vary? Do they use 1920x1080 on any? Or 1280x720?I know they've used odd resolutions before - don't they use 544x480 for SD? Thanks. I read the 1440×1080 somewhere.

I know they’ve used odd resolutions before – don’t they use 544×480 for SD?

MPEG4 issues. But a tiny correction...DBS (at least DirecTV) has actually been using 1280x1080 for its 1080i channels. A bizarre resolution, I know, but that's what it is if you examine the actual MPEG2 recordings on the HR10-250, anyway. And on even a moderate-quality display, the difference between that and OTA is quite noticeable to my eyes, assuming the OTA broadcast isn't being overcompressed to allow for several subchannels.
