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?

Title:
  HVR-1300 HVR-3000 HVR-4000 broken in kernel

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Triaged
Status in MythTV:
  Invalid
Status in “linux” package in Ubuntu:
  Triaged
Status in Debian GNU/Linux:
  New

Bug description:
  This is a continuation of bug #436564. Please refer to that for relevant dmesg'.
  The capture card I have is the Hauppauge HVR-1300.
  The card is now correctly recognized as DVB-T but channel scan fails with message "Timed out, no signal" at each channel is scanned.
  The command scan <location> > channels.conf ends correcly and file channels.conf is feeded with all tunable channels.
  I tried to import such channels.conf with the same result.
  Increasing the signal and channel timeout in the DVB settings (now up to 1000 but I planned to increase to ignore) doesnt solve the problem.
  Tonight I will try what Marc suggested - mythtv-setup --verbose channelscan,siparser,channel,record - then I will report the log.
