[mythtv-users] [OT] Simple script to initialize multiple PVRs

[Jurgen Kramer]

With my limited programming skills a wrote a little script which
automatically sets the necessary ivtv parameters at bootup. I run this
script from rc.local.

BTW it currently only handles 150s (500s) and 250s and it is set for PAL
BTW2 enhancements / additions / simplifications are welcome!
