[mythtv-users] HD-PVR: Suggestions on what to try next?

[Greg Hormann]

Ah, HD-PVR.  Such a cool device if I can get you to work with mythtv. :-)

I have a new (Rev F1) device going into a mythtv 0.24 system.  I can
use "cat" to create a test file that is viewable via vlc.
Unfortunately, the Mythbacked throws and endless loop of "eno:
Resource temporary unavailable" errors when I to use it.  Also, after
myth is done, cat no longer works until I powercycle the HD-PVR
device.

Using Mythbuntu 10.10 with 2.6.35-28 kernel.  I used the supplied
HD-PVR CD in a windows system to load the firmware (0x15 per logs).
Because my device was not recognized (new USB ID), I had to compile my
own v4l-dvb using the old mercurial repository as outlined
http://www.mythtv.org/wiki/Hauppauge_HD-PVR.  (I tired the new
media_build repository too, but hit some compilation errors I couldn't
resolve.)

Everything works fine outside of myth. (IR Blasting, IR Receiving, and
cat /dev/video) so I'm stumped.  I know a number of folks have this
working, so I'd  love some guidance on what to try next.

Thanks so much!
Greg

$ cat /dev/video0 > test.ts
^c
vlc test.ts  <-- Nice 1080i video! Yea!

Start up myth-backend; Record light on HD-PVR doesn't light up

$ tail -f /var/log/mythtv/mythbackend.log

stop mythbackend

$ cat /dev/video0 > test.ts
cat: write error: Bad address
