I guess, but it's pretty clear each has different types of problems with mpeg 4. Personally, I think lack of sharpness and ghosting is better than complete pixelization and audio and video drops, but that's up to you.
As this is a DirecTV thread and I was asked about Dish locals so I'll be brief.
This is also specific to SF bay area Dish local HD channels, I have no idea if or what problems they are having elsewhere, although a look through the threads does produce some information that the SF problems are not totally isolated.
The 720p stations here, ABC and FOX seemed to have the best PQ although there is an ongoing issue with audio-sync with the ABC station.
The 1080i stations, CBS and NBC have various problems from ghosting to stuttering video-I recall reading somewhere in this forum that the Dish MPEG4 encoders were having problems with 1080i content although I have no specifics.
All 4 of the stations have a soft look and the colors are somewhat washed out when compared to a Comcast feed which in this area is full rez/full bitrate, conversion to QAM being the only signal manipulation.
I have not seen any pixelization or any dropouts that I can recall.
The washed out look could possibly be improved by calibrating the STB to the display and is something that I'm getting done anyway as is time again to do the whole system. The rest of the problems can only be fixed by Dish in my estimation, and I hope they have them worked out before the fall season begins as I would prefer to be able to drop Comcast-at this point in time, the Dish PQ is not acceptable enough to do that.
The above observations made with a Dish 622-HDMI and component, feeding a DVDO VP30-HDMI out to a Mits 9" CRT equipped 73' RPTV.
(Guess that wasn't very brief now that I see the post itself..
