I flashed my TP to vzn (vzn leaked ROM) and the TV out prog was not included. I used the cab from #6 on this thread..

I dont get a icon in programs but when I plug in the cable it runs like it did when my TP was on the Sprint Rom.
Hope that helps!
Maybe someone smarter than me can figure out the icon thing.....
