Hello,
My driver for the miro PCTV is more or less in the same status than
yours, but I've stop coding and begin to think in writing a i2c-usb driver
for the nt1003, to be able to use the drivers that are actually used by
the bttv and the rest of v4l stuff. Doing so, there is no need of rewrite
the tuner driver and also the saa7111 driver can be used with minimal
modifications. The problem is that I think I don't understand yet how the
new i2c driver works, and I'm not sure if this can be done. Have somebody
done this kind of mix? don't you think this is the better way to develop
the driver?.
Cheers.
Nacho.
