It took me a few weeks to have a closer look at the problems but I do have
made progress so here I am again with some news.

I've had a look at this and the driver definitely supports setting
frequencies because I've found the following code in the setchannel binary
of the pvrxxx driver.

ioctl( tfd, TVTUNER_SETFREQ, &freq )

I currently don't know how mythtv detects the prvxxx driver but probably
it is not doing it correctly and this is why it does not use the
frequencies.

p5-xmltv was already updated from sylvio@ to 0.5.53 and i've also talked
to him about updating it to the latest version 0.5.57 so this will also
happen in the future. Does 0.5.53 already work for you?

I'm not sure yet what is going wrong there because the mythtv code in that
files did not change significantly since 0.22. From the output is looks
like mythtv misdetected the driver and does nonsense. I've added a patch to
the mythtv port to output a few more debugging infos about the driver right
after the "Not ivtv or pvrusb2 or hdpvr driver" message. So please
recompile mythtv and send me the output again so that I can hopefully get a
clue what is going wrong with pvrxxx.

VDPAU support should already work fine since the last nvidia-driver update
and I have also patched mythtv to compile with enabled v4l support now.
Why? Because finally I decided to buy a Pinnacle PCTV 452e (USB) device
that supports DVB-S2 and play around with webcamd to get it working in
mythtv. I'll let you all know as soon as I have success. 

That's it for now! Happy testing.
