|Re: [PLUG] MythTV & HDHomeRun & Comcast Digital for Pottstown/Collegeville|
Two other things have occurred to me leading to a bunch more detail.First, in http://lists.netisland.net/archives/plug/plug-2011-08/msg00023.html Matt said: "4) Comcast doesn't transmit the channel information in a manner that can be interpreted by MythTV. You will have to do a channel scan, and manually tell it which frequency/program ID matches to which "channel" in the listings."
That seems to imply the "channel scan" should Just Work, so either it doesn't, I've missed something, or I'm interpreting the results wrong. Which leads me to...
Second, I've been assuming that a "channel scan" should Just Work now, partly because the TV Just Works for lower channels. But I'm sure the TV has both analog and digital tuners and it user what it needs, while I think the HDHR3-US is digital only...
I've ended most of my tests after channels 2-12 or so have failed, but maybe they *should* fail until Comcast flips the switch on the 13th? Or maybe "timed out, no signal" isn't actually bad?
So I ran a "Frequency table = cable; Modulation = Cable (QAM-256)" scan and in addition to the things I listed in my last message, I also got:
QAM-256 Channel N -- timed out, no signal QAM-256 Channel N -- timed out, Y possible channels QAM-256 Channel N -- timed out, no channels QAM-256 Channel N -- Found Z probable channels Program Y, Encrypted After it (finally) finished I got: Found 25 new non-conflicting ATSC channels = Insert all Found 2 new non-conflicting MPEG channels = Insert allFound 5 new conflicting SCTE channels = Insert all (then manually took the "suggestions")
Found 29 new conflicting MPEG channels = Ignore allWhen I then looked at the "Starting channel" pulldown, the list looks suspiciously like what I expected it to look like, based on channel surfing the TV. WTH?
Then for the second tuner I did the same thing and got: Found 7 off-air channels = delete all Found 25 old ATSC channels = Update all Found 2 new non-conflicting MPEG channels = Insert allFound 5 new conflicting SCTE channels = Insert all (then manually took the "suggestion")
Found 29 new conflicting MPEG channels = Ignore all What does all of that mean? Then I go in to "5. Channel Editor" and get a mis-mash of stuff.Once I fire up the backend and a front-end, and go to the "Program Guide" I do see new stuff, but almost all of the new stuff is "Unknown (Unknown)". OTOH, a few new things do show up (some new PBS'), correctly and a few things are dups (I think I edited some names long ago, so now I have e.g., "9 Fox WTXF" & "9 WTXF" and "14 PDB WLVT" & "14 WLVT Lehi..."). I have created a new "lineup" in SchedulesDirect, linked that lineup to the new tuners and run 'mythfilldatabase'.
Does that all go back to Matt's comment, and if so how do I fix it?Also, any clues what, if anything, I need to do or re-do when Comcast flips the switch on 2011-09-23?
Finally, "Watch TV" (AKA old "Live TV") doesn't work now. It just goes black for a few seconds and then comes back. Having said that, we never use that so it may have been broken for a long time and have nothing to do with anything current...
Clues?
