IceTV on my Win7 Media Center keeps changing the mapping of Channel 92 - GEM to the guide for 9HD. I manually have changed it a number of times to link 92 to Gem-IceTV, but within a few minutes it changes itself back to 9HD-IceTV. Channel 90 is also (correctly) mapped to 9HD-IceTV.
How do I make sure that 92 displays the GEM giude, not 9HD?
