I got a prompt conserning hcwhdpvr.ax The file in the beta (18.104.22.168) was earlier than the version that I had installed from the 1.0B drivers (22.214.171.124). This causes a do you want to overwrite the newer file popup. I said yes, the drivers installed.
I then opened TME and start the capture tool which sees the HDPVR. The preview window shows fine. If I hit Device settings, things are fine. But if I hit "Format Settings", I get a popup error
Error:GetAudioEncoder() failed hResult 0x80070490
After I hit OK on the error message I do get a screen where I can select AAC or AC3 for two channel audio sources. No where do I see choices for 5.1. My hdpvr is currently not connected to the SPDIF so that might be the reason.
I have to go out for a few hours... will post more later
