[mythtv-users] Frequencies]

I already tried that option.  The problem seems to be that the tuner
(TCL2002N) isn't fully supported yet.  There was a suggestion over on the
Video4Linux list to modify tuner.c but the version of ivtv (0.2) that I
have doesn't have tuner.c.

The card setup has been confirmed with ivtcl (0.2 replacement for
test_ioctl).  If I start MythTV and then go into a terminal window I can
run ptune.pl there and pass a frequency number that I have previously
determined will be on a channel.  MythTV then shows that video/audio
perfectly.  Based on that I think that the card is set correctly but the
tuner is getting tuned incorrectly.  When the driver loads at boot it is
setting the correct tuner type.

to the correct frequency based on normal channel numbers.  I need to be
able to control the frequency that is passed to the tuner... In other
words, I need to  have a Custom Channel to frequency table.  OR buy an
older PVR 250 with a better supported tuner.

I posted this just two days ago to the list in answer to another
question about finetuning so you might try searching the list archives
before posting.
