Uh-oh.  Here comes a grand display of my ignorance for the manual
workings of this device.  :-/

Primarily I use this device with Mythtv but have been forced into trying
to debug this as it's not working in Myth.  I thought that using this
device was as simple as one of the PVR-{50,{1.2}5}0 devices and I could
just "cat < /dev/dvb/adapter0/dvr0 > file.mpg".

Your reference to azap gave me something to research.  Subsequently I
have done the following:

$ brian@pc:~$ w_scan -c US -x -A2 > /tmp/initial-tuning-data.txt
$ mkdir ~/.azap
$ scan -A2 initial-tuning-data.txt > ~/.azap/channels.conf

But now I can't get azap to do anything useful:

$ azap -r 291
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
ERROR: could not find channel '291' in channel list
$ azap -r 145
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
ERROR: error while parsing modulation (syntax error)

Not sure what to try next.

b.
