Hi apparently this is a problem related to the new behavior of udev under Debian. I wouldn't recommand to downgrad udev though. I read the following on videolan's website: if you have a distribution that uses udev, then you must add/change the following line to the file 50-udev.rules in your /etc/udev/rules.d directory. %vi /etc/udev/rules.d/50-udev.rules # IEEE1394 (firewire) devices (must be before raw devices below) KERNEL=="raw1394", NAME="%k" KERNEL=="dv1394", NAME="dv1394/%k" KERNEL=="video1394*", NAME="video1394/%n" I havent tested it yet, since i havent any DV cam before hand at the moment. The workaround i used at the time is the following: first check that you belong to the right groups : disk and video by issuing the command groups If not, then $ sudo adduser username disk $ sudo adduser username video then run the attached bash script as a superuser after each restart: $ sudo bash ./dv.sh you might have to chmod +x the shell script Start Pd/Gem, pix_video should work as expected if feeded with the pathname given in the shell script (I cant remember well this part, i'm sorry i'm only sending a translation of my blog notes, i dont have access to the original machine and Pd program this week (public holiday).) The shell was adapted from an article about Ubuntu Edgy and DV cams http://tonywhitmore.co.uk/blog/2006/11/08/ubuntu-edgy-and-dv-cameras/ O.
