Thanks for your reply.

Distro is Arch Linux 06.2008, /dev/raw1394 has full permissions
for all users, all modules are loaded and I tried various values for dv 
caching ranging
from 100 to 10000. I tried dvgrab if there isn't an hardware or kernel 
error but
dvgrab works perfectly.

I've just noticed something strange. Syslog gives this message:
raw1394: old iso ABI has been removed.
does it mean that dv access/demux module could be using some deprecated
API functions? If it does, is someone working on update? If not I suppose
I could try to do that sometimes next week, I really need that one working.

thanks for any info.

V.K.
