Actually, it turned out that the vbi entry wasn't the problem.

I've filed a ticket with the patch that works with the updates in
v4l2-ioctl where EINVAL has been changed to ENOTTY for unimplemented calls.


This fixes the problem for me with saa7164 (HVR-2250) and analog
recordings without touching the DB.

I'll likely go in and recreate the capture cards anyway in the coming days.

Thanks, Mike.
