Adding HD-PVR in preparation for 0.22

OK, so I bought an HD-PVR and I want to make sure its working outside of
Myth before I upgrade to 0.22. I'm currently running the following on
Mythbuntu 9.04 x86_64:

hdevine [at] hdevine-deskto:/tmp$ mythbackend --version
Please include all output in bug reports.
MythTV Version : 21768
MythTV Branch : branches/release-0-21-fixes
Network Protocol : 40
Library API : 0.21.20080304-1
Options compiled in:
linux profile using_oss using_alsa using_pulse using_jack using_backend
using_dbox2 using_dvb using_firewire using_frontend using_hdhomerun
using_iptv using_ivtv using_joystick_menu using_libfftw3 using_lirc
using_opengl_vsync using_opengl_video using_v4l using_x11 using_xrandr
using_xv using_xvmc using_xvmcw using_xvmc_vld using_glx_proc_addr_arb
using_bindings_perl using_bindings_python using_opengl
using_ffmpeg_threads using_libavc_5_3 using_live

My Update Manager says that 9.10 is released and I wanted to get the
HD-PVR working before I upgrade. I just hooked it up and tried to
capture from it (cat /dev/video0 > /tmp/test.mpg) and got the following
when I try to play back the file:

Forced audio codec: mad
Opening audio decoder: [libdv] Raw DV Audio Decoder
Unknown/missing audio format -> no sound
ADecoder init failed :(
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
Cannot find codec 'dvaudio' in libavcodec...
ADecoder init failed :(
ADecoder init failed :(
Cannot find codec for audio format 0x56444152.
Read DOCS/HTML/en/codecs.html!
Audio: no sound
Video: no video

Any ideas/gotchas that I need to look out for in order to verify its
working before I take the plunge? I have the Component Out from my
Comcast cable box to the Component in on the HD-PVR. That's all I've
hooked up. I didn't do anything with the outputs on the HD-PVR as I
didn't think it was necessary..

Thanks for any ideas.
Harry

Anyone? Anyone at all? I do notice that I only have 1 video device
under /dev (/dev/video0), and that is the device for the analog portion
of my pcHD5500 card. So how can I see if this box is working? Like I
said above, I have the component (red/blue/green) cables from my Comcast
Motorola box into the Input of the HD-PVR, and the HD-PVR is plugged
into my Myth box via USB.

Any ideas? Am I missing something very obvious?
Harry

If you don't have a video node for it, the box isn't installed
properly. Since you are using 9.04, you will need to compile and
install v4l-dvb from source and modprobe the hdpvr module to be able
to test it.

Will upgrading to Mythbuntu 9.10 help? I know that it was coming with
0.22 on it, so wouldn't the v4l-dvb apps and hdpvr module be there
then? How are other people hooking their HD-PVRs up? Are they
compiling v4l-dvb too? Perhaps I missed that somewhere as I thought I
could just connect it via USB and have it recognized and work.

My kernel right now is:

Linux hdevine-desktop 2.6.28-16-generic #55-Ubuntu SMP Tue Oct 20
19:48:32 UTC 2009 x86_64 GNU/Linux

I've been holding off upgrading until I watch all of the recordings that
I've been meaning to catch up on. If it fails for some reason, I'd just
nuke it and start over. Not a big deal to me.

Thanks,
Harry

Yes, the kernel included in 9.10 includes hdpvr drivers.

That's not the relevant part. The relevant part is the kernel version.
The kernel in *buntu 9.10 is sufficiently new enough as to include the
hdpvr driver though.
