[Kwintv] kdetv not working with Terratec 600

[Karl Ove Hufthammer]

I can't get kdetv (CVS version) to work with my Terratec 600 TV/Radio card.
I *have* read the FAQ.

Here's the (possible) relevant messages I get when starting kdetv:

...

Too many errors. Ending V4L2 grabbing.

At this time I get a dialogue saying 'Can't record video [...]' before I'm 
able to select 'Television' and 'PAL' in the channel wizard. When I do that, 
and start the channel search, I get:

...

kdetv: WARNING: V4L2Dev: VIDIOC_S_FREQUENCY failed: Invalid argument
kdetv: ChannelScanner: Station found: E4, frequency: 62250 kHz
...

Whether it finds the channels varies (it depends on the v4l settings, AFAICS), 
but the result is always the same: Nothing is displayed (only the black 
background).

No matter what I set the v4l or v4l2 settings to, I get error message 'Can't 
record video ...' (translated from Danish).

tvtime works perfectly (with the default settings), both in window mode and 
fullscreen. Zapping does not (complaining about 'not enough buffers').

Any ideas?
