We had a PC running Vista Ultimate with a Hauppauge Nova PCI dual tuner DVB receiver hooked up to a little stick antenna using Windows Media Center.

Reception on some channels was sometimes a little flaky but then for the last week the video has been pretty much frozen and jittering on all channels but the audio was fine.

At first we thought it might be weather conditions or transmitter changes so re-tuned the channels but still had problems. I then remembered someone had install updated ATI Radeon X1650 drivers and the catalyst control panel.

Although these drivers seemed newer than Vista’s own uninstalling the drivers and catalyst control center and reverting back to Vista’s native drivers restored perfect TV playback in Media Center.
