[mythtv-users] Ugly TV Capture/Blank LiveTV with PVR-250

Here is the output of my modprobe tveeprom:

tvee: Hauppauge: model=32032, rev=B326, serial#=7194195
tvee: tuner=Temic 4036FY5 (idx=26, type=8)
tvee: tuner fmt=NTSC(M) (eeprom=0x08, v4l2=0x00001000)
tvee: audio_processor=MSP3440 (type=11) 

I tried changing my ivtv option "tuner=39" to "tuner=8" and I did get some
channel audio, but the video was static. Is this the correct type?

Thanks for the help...

Sounds like 39 is the wrong tuner type.  What's the output of modprobe 
tveeprom (it will be in /var/log/messages or the output of dmesg).
