Interesting, thanks for your work. I have two questions:
1. I get one of the following on all frequencies:
tuning 555000000hz.....no lock
tuning 561000000hz.locked...PID 0x1ffc timeout
Does that mean that in my area no info is available at all?
2. Is the virtual channel map that you are describing the same or
related to the VCT table that is part of ATSC standard (but that uses
pid 0x1FFB)? I guess not, because Comcast does provide limited VCT info
(for broadcast channels only) and both TV and Myth can see it. So, this
must be something else? Can you point to a spec?
Thanks,
Bolek
