Hi,
I was trying to set up my WinTV PVR 150 so I can watch TV while using
Linux. I'm using Gentoo as a distribution and was largely following the
howto (<http://ivtvdriver.org/index.php/Howto>) in the IVTV wiki.
I installed the necessary firmware (there's a Gentoo package for that)
and Udev automatically loads the ivtv driver during boot, which seems to
work fine. The video devices are created without any problem, but every
attempt in capturing or viewing TV fails. I tried to use the ptune-ui.pl
script and set a channel while using cat /dev/video0 > test.mpg to
capture the video but the resulting file contains only static noise. I
tried kdetv (which sees the card and lets me choose the same channels as
ptune-ui.pl) and that only displays static noise for every channel. I
tried to use xawtv and that only displays a black window.
Here the output of uname -a:
Linux rhuidean 2.6.22-gentoo-r8 #3 Thu Oct 11 21:03:21 CEST 2007 i686
AMD Athlon(tm) XP 2500+ AuthenticAMD GNU/Linux
Here the relevant dmesg output:

I already use that card regularily from within Windows 2000 where it
works (well, except the IR remote control, which I haven't tried with
Linux but somehow doesn't work with Windows), so it's probably not a
hardware problem.
As an additional information: I live in Germany and want to use the card
to watch the analog cable program I receive here (which works using
Windows). I selected »pal-europe-west« for "frequency table", tried
PAL-BGH, PAL-M, PAL-I and PAL-DK as standards and selected "tuner 1" as
the input source (in ptune-ui.pl).
Oh, and while capturing or running kdetv, no additional kernel messages
are generated.
As far as I can see, the driver seems to recognize the card and load the
firmware. And reading /dev/video0 I get an MPEG stream so the decoder
itself seems to work. My guess is that the tuner somehow doesn't set the
correct channel - but why? Any ideas?
Thanks,
Christian
