So i finally get everything working last night and im playing with my system until like 3:00am when i hear a loud pop. Now i get no pvr output, i've tryed everything but reloading the dang thing. Is there anyway to manually tell the pvr to tune to channel three besides the mythtv setup channel editor thingy. I'm hoping and praying it didn't explode on me last night. It was finally working perfect, took me 8 months to get this thing where i wanted it (mostly because of money issues).
