Hi,
I am running MythTV 0.20.2 for some months without problems. I am using
a PVR-350.
Recently I tried to add a second capture device, an MSI MegaSky 580 USB
DVB-T receiver.
It works in principle; I scanned the channels to a channel.conf and can
watch TV with mplayer.
Then I tried to install it in mythtv. I first tried to scan the channels
- it worked; but when I tried to watch TV, I see only white noise on the
screen. I tried to import from channels.conf - same effect. I manually
deleted the corresponding entries from the sql-table 'channel' and
'dtv_multiplex' and imported channels.conf again - same effect.
I also corrected the 'mplexid' bug - same effect.
Watching TV from the PVR-350 works fine as before. In the
mythbackend.log, there is only one entry 'TVRec(1): HW Tuner: 1->1, also
wenn switching from PVR-350 to MegaSky 580 channels - may this be an
indication that mythtv tries to use the PVR-350 also for the MegaSky 580
channels?
For reference, I append the channel and dtv_multiplex tables:
> mysql> select * from channel;
