At least every 90 minutes (if I'm lucky) I lose the ability to operate DISH NETWORK through Sony's GTV. It locks up! I cannot access the guide, change channels, or go to my homepage. Eventually I get a popup that says "FORCE CLOSE" "WAIT" or "REPORT" Force Close is the only option that lets me view TV again. I have called DISH NETWORK and SONY and they both blame each other. Dish Network works 100% GREAT when not in use with Sony's GTV and always has! Sony's response was that Sony's GTV freezes because it cannot handle HDTV and that I should only watch channels that are standard def. (which makes zero sense since it comes bundled on an HDTV). Anyone else having the same problem? Any real solution?
