Noticed tonight that HD Theater is now also on channel 281. Is this MPEG4? I no longer have any MPEG2 only IRD's in my home. IMO it looks a little soft just like ch 76. Is this a mirror of the HD Lite MPEG2 channel? Also noticing some motion artifacts.

I don't have any inside info on this (in fact, haven't tuned in to the channel), but your description sure sounds like they're just mirroring channel 76.

There's no Channel 281 on MY Directv.

You might have it unchecked on you favorites list. I had to add it manually on my HR20..it showed on my H20 without having to add it. Tune to it directly. I'm watching it now.

I get 281 on my HR20 but not on my HR10 which suggests it is either a remap or an MPEG4 channel. I believe it is just a remap because 76 is still up and it wouldn't make sense to dedicate that much bandwidth to one channel.

Remap, note that the channel name is Vitrual. Lyngsat has incorrect data that the channel is mpeg4
