Here's the script I use to delay until the udev permissions are set on my 
tuner (ie group is video instead of root).  I post this because A) it 
might help you and B) if anyone has a better way of doing this I'm 
listening.  I'm a programmer but not a bash expert.  It seems like this 
should be possible without a temp file but I couldn't get it to work and 
it was getting late the night I was messing with it.  I'm sure there are 
other ways to check permissions, too.

while true; do
        find /dev/video1 -group video > /tmp/waitForVideo
        if [ `grep video1 /tmp/waitForVideo` ]; then
        sleep 1
