Hi Adam, It is possible I trimmed it to not spam the mailing list. As I do not remember, I generated fresh logs. It definitely works though as I used that old kernel to rip a few tapes. The following is from 2.6.35-rc3 on Ubuntu 10.10: $ dvgrab -noavc -guid 00808801035809f1 -d 1 libiec61883 error: Failed to get channels available.

Thanks for the hints and the reference. It does generate cleaner and more readable logs this way. I also didn't know one can just capture from camera mode through firewire, which simplifies things.
