#1779: QAM scan does not find all channels
---------------------------------+------------------------------------------

---------------------------------+------------------------------------------
I'm using QAM with Comcast in San Francisco. I was using channels.conf
import before but now I'm trying the Myth scan.
With the signal timeout at the default of 500ms, virtually nothing was
found, just a bunch of music programming on 127. After increasing the
timeout to 3000ms, lots of stuff is found, including many of the channels
I'm interested in. However, Comcast also carries all the local channels
in standard-definition digital on channel 93. The scan doesn't find any
of them. Increasing the timeout to 6000ms doesn't seem to make any
difference.
I'm attaching a log of "mythtv-setup -v siparser,record,channel" and a
also a bit of a dump from dvbsnoop with the card tuned to channel 93 (this
shows that there are indeed a bunch of channels on 93). The interesting
thing is Myth does see SOME channels on 93 -- it gets 93_6 and 93_8 -- but
93_{1,2,3,4,5,7} are also just fine and happen to have all the major
network programming in SD.
For examples where the scan seemed to work well (including finding
callsigns, though they don't match Zap2It's callsigns), see channels 111,
113, and 114.
Please let me know if I can provide any more information.
Thanks, Steve
