I having been having this same problem and I use the coax analog input
from my Dish (Expressvu) satellite box into my PVR-350.  I need the card
to be tuned to channel 4 and have set this in the input connection screen
as the previous poster has mentioned.  What I am curious of is how it was
resolved.  Did you just delete the "Preset Channel to" number and leave it
blank?  Has anyone else had similar issues and what was your resolution? 
My script works fine manually from the command line.  Note that Live TV
doesn't work either and I suspect it's related to channel problems of some
related nature.
