Hi Arnout,
Sorry for the delay, I was away on business.
First check if you have the correct cx25840 firmware (14264 bytes long).
If not, switch to that and try again.
If you are using the correct firmware, then please enter a bug report
('ticket') here: http://ivtvdriver.org/trac/newticket
Please also attach a file with the IVTV INIT messages from the kernel
log when you enter the bug report. After entering the ticket you can
attach a file with those IVTV INIT messages.
I don't have time right now to look into it, but I hope to be able to in
the near future.
