[mythtv-users] MJPEG cards?

Hello everyone.
I'm trying to get MythTV to work with a TV card that has an MJPEG
hardware codec. The card is a Pinnacle DC10Plus, and it uses the Zoran
ZR36060 chip. It does not have a tuner, because it's designed for video
editing and such. It will work for my purposes, since I am using a
cable box anyway.
I do not understand if MythTV even supports using such cards. The
documentation briefly mentions using one such card, but I am not sure
how to set it up. Right now, I have a MythTV 0.10 install. The card is
properly installed and works with mjpegtools. When I try to watch TV, I
get a big stream of errors from the backend (and a blank screen on the
frontend):
VIDIOCSYNC0: Invalid argument
VIDIOCSYNC1: Invalid argument
VIDIOCSYNC0: Invalid argument
VIDIOCSYNC1: Invalid argument
VIDIOCSYNC0: Invalid argument
VIDIOCSYNC1: Invalid argument
and so on...
The backend also shows the following when it starts up:
Starting up as the master server.
Probed: /dev/video - Composite
Probed: /dev/video - S-Video
Probed: /dev/video - Internal/comp
VIDIOC_S_STD: Invalid argument
Any ideas? I would really like to get this to work, since using
NuppelVideo is not possible on my slow 700MHz machine.
Thanks.
