Comment 160 for bug 439163

My hvr 1300 doesn't seem to work no matter what I do. The symptoms are the same for all 2.6.37.x kernels; the cards IS recognized - dmesg | grep cx88;

I've also tried different module options amongst oithers different tuners like; option cx88xx card=56 tuner=63 (1,3,5,7,41,43 ...)

No logs in /var/log shows anything suspicious. If I start scan, me-tv or Kaffeine nothing happens, and nothing in the logs. All three ends up as dead processes and can't even be killed properly.

Furthermore I have tried dvb/v4l from git and also compiling my own kernel. I have also applied the small hack to the cx88-dvb.c file in the source for my particular card as described above.

Nothing works so far. The card use to work under earlier kernels up to 2.6.33 on Ubuntu.
Where to go now?
