I'm in San Francisco Bay Area using HD3000 to get OTA channels. I
can't record/watch channel 36-1 (KICU).
Quick question for any DVB developer, what is "atscsrcid" and how do I
find it ? This channel had for some reason \N \N in its serviceID and
atscsrcid in the dtv_multiplex table. I ran dvbscan to find the
serviceID which is 3. I still dont know what is atscsrcid and how to
get it. I kept trying a number from 1 to 10, but still get same error
messages when trying to record in myth.

================================
When I run azap it seems fine. The "unc" is always 0. That means there
are no uncorrectable errors.
