Uh, within limits :-)
I just tried my DC10 and it works a little bit. Meaning that I did manage
to capture, but that the V4L2 implementation is so bad that I basically
was unable to use the qv4l2 capture utility.
A lot of the problems usually disappear if the driver is converted to use
the videobuf2 framework.

Is there a reason why you want to work on this? Otherwise I would just
leave it and eventually I will rework the zoran driver. When that will
happen is something I don't know.

I haven't seen any requests for help in a very long time, so I suspect very
few people, if any, still use it. I'm crazy enough that I like cleaning up
old driver code and getting it to work again, but that's just me :-)
