[mythtv-users] HD-PVR blues and 0.22 - wrong video node

[Bob Sully]

Hi all -

More 0.22 break-in blues.

I have an HD-PVR.  Under 0.21-fixes, I used it to record by running a
little script I ran manually.  Worked fine, though I had to ssh into the
Myth machine in order to record something if I wasn't home.  I was
compiling the driver myself, as I was running Ubuntu 9.04 with an older
kernel which didn't include it.

I am now running Ubuntu 9.10 with the 2.6.31-14 stock kernel.


I have a pcHD-5500 card in the machine which is /dev/video0.  The HD-PVR
should be assigned as /dev/video1.  It was assigned that node before, as I
have this:

options hdpvr video_nr=1 default_video_input=0 default_audio_input=2

in /etc/modprobe.d/hdpvr.conf, and the following in
/etc/udev/rules.d/50-custom.rules:

# HD-PVR
KERNEL=="video*" , ATTRS{product}=="Hauppauge HD PVR" , NAME="video1"
KERNEL=="video1" , MODE="0666",   SYMLINK+="video"


Under 0.22, mythtv-setup sees the two tuners where they should be, when I
assign capture cards - the pcHD-5500 on /dev/video0 and the HD-PVR on
/dev/video1.

However, I tried scheduling two recordings on the HD-PVR tonight, and both
failed.  Log states "Canceled recording - recorder failed".

I tried recording manually (cat /dev/video1 > test.ts).  This worked
perfectly well before.  Now, I only get audio...which I think is from the
pcHDTV card (which had last recorded from ABC; the STB was set to FX-HD;
the audio was from an ABC show), and no video:

mplayer test.ts

BUT...while recording, the LEDs on the HD-PVR DO light up.


Looking at /var/log/syslog, when I power-cycle the HD-PVR, I see this:

Nov 16 22:49:01 vader kernel: [ 4440.100268] usb 2-3: USB disconnect,

Nov 16 22:49:37 vader kernel: [ 4475.980827] hdpvr 2-3:1.0: device now
attached to /dev/video0

However, looking at the two nodes:
[mythtv at vader: /video]$ lsl /dev/video*
crw-rw----+ 1 root video 81, 1 2009-11-16 21:35 /dev/video0
crw-rw----+ 1 root video 81, 0 2009-11-16 22:49 /dev/video1

/dev/video1 is obviously assigned to it, if you go by the file creation
times. Yet, it doesn't record.

I tried rebooting the Myth machine.  No difference.

This is really baffling.  Can anyone give me a sure-fire way to make sure
the right node gets assigned with the Ubuntu HD-PVR kernel module??  I had
it working reliably before.

Thanks for any help you can offer.
Bob
