I've been trying to deal with this myself ever since udev showed up. I have 2 DVRs, 1 has 2 identical Hauppauge PVR-250 cards, but they are just straight NTSC cable, so it doesn't matter which is assigned /dev/ video0 at boot. But the other machine has 1 PVR-250 attached to my cable box, 1 pcHDTV 3000 and a webcam. So far, the webcam always seems to be / dev/video0, but the PVR-250 and the pcHDTV seem to be randomly assigned / dev/video1 and /dev/video2, which means I have to manually check by running mplayer /dev/video1 to see if it is the PVR-250. What really sucks is if I'm gone and lose power, when it reboots it may come up with the 2 cards switched and a timed record will of course be screwed up. BTW, does anyone know why the pcHDTV 3000 does NOT use /dev/videoX ? It uses /dev/dvb/adapterX/dvrX. Is there a techinical reason why the device driver authors chose that instead of /dev/videoX ? It does make "roll- your-own" DVRs harder to write. (I hate MythTV)
