[mythtv-users] Re: Error tuning. Cant get PMT's (MythTV)

[Forest Lynn]

Hi, 

I had the same problem.

I just upgraded to mythtv 0.17, kernel 2.6.11 and air2pc (replaced the
HD-3000 for alleged better reception). The channel scan in mythtv
setup found 5 subchannels for a ATSC channel (PBS) with strong signal,
and I know all of them exists in the air since I could receive all of
them in mythtv 0.16 using HD-3000 (V4L driver), but now I can never
tune to subchannel 5 due to this "Timeout Getting PMT" issue. All
other 4 subchannels work fine.

I did not try the "azap" the "dtvscan" since I don't know how to
create my own frequency/channel table (the script did not work for
me), so I am not sure whether this is a driver problem or mythtv
problem.

Really hope somebody can shed some light on this issue because most of
the time that missing channel is the only channel I care, and is the
only channel that carries HD-signal in the five subchannels.

Thanks in advance for any suggestions/fixes.

Warren
