[mythtv-users] Error setting tuner type with PVR-350

Sat Jan 31 20:23:22 EST 2004

  I've been in the process of setting up a new MythTV box and for the most part things have gone pretty well. I have a PVR-350 card and was able to getting the TV-out working and am able to capture using the S-Video input. However, I'm having trouble loading the tuner module. If I have the line "options tuner type=2" in my modules.conf file, then ivtv doesn't load and neither does any audio drivers. I'm running RH9 with ATrpms and have been following Jarod's guide. I know this may be more of an IVTV question but that list doesn't seem to have much activity and I figured that there are a lot of people using the 350 with MythTV. Any ideas?

  I've included my modules.conf file and output of dmesg below. In the dmesg output, you can see that right after the "tuner: chip found @ 0xc2" line something bad happens and a stack trace is printed. If I comment out the "tuner type=2" option in modules.conf, this doesn't happen and the modules are loaded fine.
  Thanks in advance for any help you can offer!

  ----------Snip of dmesg output---------------

  I got that same problem just after I updated bttv. Whether that is the problem, Im not sure.
  I just re-started from scratch, as I didnt really want my bt8x8 card there anyway - So I took it out
