    My bet is the compression protocol Comcast is using to cramp more HD channels over the same coax. DirecTV is going to MPEG4 to expand their HD lineup. Not sure whether using the newer DirecTV's H21 HD receiver or HR21 DVR have the same viewing issues.

    Like I had indicated earlier, I have the same TivoHD unit going through HDMI to another similar size LCD TV but without the receiver in between; and unfortunately I am seeing the same pixelation issues. Another proof is I still have a Comcast HD receiver connected to a HD 34" CRT TV and I saw major pixelation on fast motion HD movies.

    Again, to the best of my knowledge, Comcast does not transcode. Do you have any information to the contrary?

    Sorry, but I am not aware either way whether Comcast does transcode. If they do not transcode, the issue may be the (satellite??) source downward feed that Comcast gets. Interesting point though!

    I submitted a lineup change to them last night, and they replied with a "5-7 day time frame" to update it. Hopefully sooner than later.

    I did the same thing, a few days ago. Hopefully they are getting lots of AA requests, and will step on it!

    Just saw an email from Tivo that they added the 4 new HD channels. Did not even have to re-run the channel lineup. Kudos to Tivo for the quick turnaround.

    I my area, Comcast carries all the HD channels in the 700's. I scanned all the 700's up to the premium HD channels (770) and did not find anything that looked like SciFi HD. :(

    Yeah nothing for me either but thanks for the info... I just switch to the M-card Wednesday and I tried to get information from the lady in the office but no luck... The only thing she said was they had done work in my area the week before to correct image distortion problems but no new channels... :(

    The SciFi HD "broadcast" problems on Comcast are 99.99999999% the fault of SciFi (the provider) and not comcast. Comcast does not transcode and simply passes along what they get (at least from the OTA networks) It is possible that on of the pieces of hardware that the stream runs through was/is buggy, but I too saw the frequent breakups on the Resident Evil movies the last week or so. The bitrate was insufficient for the action scenes. Call SciFi and tell them to bump the bitrate up to 18+mbps to ensure no pixelization problems or macroblocking. Its no skin off their backs. I still cannot fathom why the will cram 3 or 4 shows into a channel mux at like 5-8mbps each and padd the rest with null packets. PQ suffers horrible, the picture is terrible, and they have unused bandwidth they could devote to the streams.

    add another MI Comcast user with terrible problems with Sci-Fi HD. I use both Tivo S3s as well as Comcasts Motorola box and have seen major issues while using both. I recorded this past weeks ECW 3 times(1 on the Comcast box and 1 on each tuner of one of my S3s - SD and HD). the HD was pretty much unwatchable on both machines. it looked terrible and was so choopy and pixelated. it also had so many pauses it drove me nuts. the best part of this was that the SD recording actually looked much better than the HD version for me.

    Same experience here in Ann Arbor too; about the only show I watch currently on SciFi is Stargate: Atlantis, but BSG resumes soon. Every time there is an action scene, the video and audio cuts out and isn't restored until the scene returns to a slow pace. Is there a consensus if this is SciFi or Comcast's problem? Who should we complain to?

    I'd guess it's a Comcast issue. If your tivo was sick and couldn't keep up with recording action it would do this on all HD channels. If it is just some channels, then comcast is compressing it too much or the signal is too weak.

    This morning I found Animal Planet and SciFi HD on Comcast in Washington State (676 I believe). The program guide data is there, I found it while searching for upcoming BSGs.

    Bring on Season Four!!!

    Comcast is using HDTV-Lite for scifi where they are compressing the signal even more after they get it. They are pushing 3 channels into the space normally used for 2.

    More details can be found in this thread http://tivocommunity.com/tivo-vb/showthread.php?t=384911

    Blah. Charter just added several new HD channels in my area: DHD, IFCHD, WEHD, FUSEHD, TWCHD, TLCHD, Animal Planet HD, and AMCHD. Where is SCIFIHD??? I'd trade all of these new ones for it!!

    What is all this talk of Comcast not transcoding? It was in this very forum I read about Comcast squeezing three HD signals over the bandwidth normally used for two. Ill try to find that discussion.

    I can say that I saw fast motion artifacts when I had Comcast HD and assumed this was why. I think people referred to it as HDlite.
