Q: How does one get the fm tuner to work with a PVR 150 MCE?

For the case of a PVR-150 MCE with a TAPE-H001F NTSC tuner, since the LG TAPE-H001F tuner appears to be a clone of the Phillips FM 1236 MK3 tuner and older versions of tuner.ko handle the Phillips tuner properly, you can add the line

  options ivtv tuner=43  # check tuner.h and verify 43 corresponds to TUNER_PHILIPS_FM1236_MK3.

to /etc/modprobe.conf to force ivtv to treat the tuner as a Phillips FM 1236 MK3 as opposed to an LG TAPE-H001F. This should get FM radio working until you upgrade to a later kernel that includes a fixed tuner.ko.

A 2.6.19 kernel patch to tuner.ko at the bottom of this message:

should get FM radio working properly for the TAPE-H001F tuner.

For Ubuntu Edgy with the 2.6.17 kernel, there is an equivalent kernel patch attached to bug 81398 in the Ubuntu launchpad.

After applying the patch, rebuilding and installing the tuner.ko module, unloading the ivtv and related modules and reloading them:

$ ivtv-radio -v -s

to scan for stations and

$ ivtv-radio -f 104.1

to tune to 104.1 MHz, for example, and listen.

I have the PVR 150 Low Profile edition:

0000:00:07.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)

And I can confirm that the fm tuner works flawlessly.
