I had been running GBPVR using my Hauppauge PVR 150 (Non-MCE) PCI card under Windows XP with no problems at all until about 3 months ago. I noticed that channels past 13 were completely fuzzy and not viewable. A few channels under 13 were this way also. I rebuilt my system and used the supplied drivers and GBPVR still had problems, as well as other types of PVR software. However, the WinTV 2000 software that comes with the PVR 150 works FINE. It shows all channels without any problems and records in good quality. I have used older drivers and the latest drivers for the PVR 150. I have taken off all splitters from my cable and still no reception past 13 under GBPVR, but it always works using the Hauppauge pvr WinTV software. Any settings I need to be adjusting? I am stumped and can't seem to find anyone else with my type of issues regarding this card and GBPVR in the forums or Google.
