I have been making recordings off of my Cable box through HDMI into my 1512 HD PVR 2. I've been recording into the .TS format and then converting to .MP4 using Handbrake to maintain the 5.1 AC3 audio. The recordings start off correctly in 720P with 5.1 audio. However, at some point during the recording, the audio gets corrupted and only comes out of the left front speaker. It seems to be happening if a commercial comes on and changes audio format (Stereo vs. 5.1). It makes the recorded movies very annoying to listen to.
Is there any way to force either the cable box to 5.1 or to keep the PVR from corrupting the file? I am working with a Scientific Atlanta Explorer 8300HDC cable box on Charter. I have the 1.3.31062 driver for the PVR.
