Public bug reported:
Binary package hint: linux-ubuntu-modules-2.6.24-19-generic
After installing Kubuntu 8.04 + all available updates (obviously it's
now called 8.04.1) I tried to install mythtv and figured out, that the
video generated by my Hauppauge PVR-150 MCE looked strange. When reading
directly from /dev/video0 the video was recognised as MPEG, but although
the card was tuned to a correct frequency, the image was quite distorted
(weird colors) and the syslog was spammed with the following:

This is just the start of the error messages, the last lines were
repeated over and over until one stopped the playback.
For me replacing the firmware-files (v4l-cx24850.fw and v4l-cx2341x-
enc.fw) in /lib/firmware/2.6.24-19 with older verions (sorry, I don't
know what version they are - I think I extracted them from the windows-
driver but I'm not sure) solved the problem (of course after reboot).
I attached the working firmware to this post. As I said, I don't know
where I got this files from, so install them on your own risk, you have
been warned.
