You saw this latest so far here from Manu 2006-12-30 ?
http://www.linuxtv.org/pipermail/linux-dvb/2006-December/015091.html

The others seem to be quite successfully using the driver, but I
followed only loosely and have no such hardware.

I wonder if the kromtek snapshot is really the latest on this then, the
files seem to indicate that latest modifications are done Oct. 2006 ?

The frontend has full debug enabled, since you caught so many bugs on
v4l2 I hope you get some feedback.

Cheers,
Hermann
