[mythtv-users] Can't record analog from Hauppauge 2255

[David Parker]

Hello,

I'm setting up a new MythTV box using a Hauppauge WinTV-HVR 2255 as the
tuner.  I know support for the card is sketchy right now, but I did manage
to get it all working (with the exception of the IR receiver, still no
support for that).  The card appears in dmesg as follows:

The two analog tuners are /dev/video0 and /dev/video1, and the two HD
tuners can be accessed via /dev/dvb/adapter0/frontend0 and
/dev/dvb/adapter1/frontend0.  I set up these tuners in MythTV and
configured their inputs, and all seems fine.  In my tests, I was able to
record HD channels without any issues.  However, I can't get it to record
analog programs.  When I try, I get a recording error in the GUI, and these
messages in the MythTV backend log:

TVRecEvent tv_rec.cpp:1051 (HandleStateChange) - TVRec[1]: Changing from
RecordingOnly to None

Weird thing is, I can tune and record from the analog tuner just fine using
other methods.  For example:

$ ivtv-tune -d /dev/video0 -c 13 -t us-cable
$ cat /dev/video0 > test.mpg

That makes a recording just fine.  I'm totally stumped.  Any ideas?

Also, and perhaps unrelated, is the fact that the card has 4 tuners (2
analog and 2 digital) but MythTV always says it has 6.  I set up all 4
tuners in mythtv-setup, it only shows the 4 tuners, but when I try to exit
mythtv-setup it tells me that the starting channel for tuners 5 and 6 are
"Please select ...".  But those tuners aren't there!  "Tuner Status" in the
MythTV frontend also shows 6 tuners.  I have deleted and re-added all of
the tuners over and over again.  Any thoughts on that will be most
welcomed, too.

    Thanks!
    Dave
