I'm new and not sure if this is the right forum but here goes. I am a Bell Express Vu user and have been recently having alot of trouble with my model 5800 PVR. My picture pixelizes randomly ALOT and I am constantly losing the signal and "seraching for transponder". I have called Bell 6 times for help. They were unable to fix the problem after much trouble shooting so they just replaced my PVR. The problem is still there though!! I have now tried replacing my Video input cable and that had no effect either. What else can I try?!?!
