I have video working fine in GBPVR 1.2.13, with Hauppauge Nova T 500 digital dual tuning cards.
However, I'm having a problem with sound for high definition TV. For the first channel I play it is okay, but after that if I change channels the sound will start for a few seconds, then the image jerks a bit, then the image goes back to normal and the sound cuts out. This is set up to use the SPDIF output. If I restart the GBPVR recording service, the first channel viewed works as it should and the same problem happens when I change.
When playing old recordings and Saturn (cable TV) channels, sound is working fine, as it's coming from the stereo output. I assume this means the MPEG2 settings are fine.
For the advanced codecs in the config, I am using Cyberlink H.264 decoder and have monogram aac selected for the other options.
