Seems I wasn't entirely correct with my discovery. The missing audio had more to do with with specific DVDs and which program I used along with AnyDVD to backup the discs. I still often use DVD Shrink along with AnyDVD because I like the GUI, but that is where I had the problem. After reinstalling the sonic encoders into MCE (they're needed to directly burn recorded TV to DVD Video within the MCE interface). When I used CloneDVD2 along with AnyDVD, the audio came back, still not synched very well, but it came back. I'm looking forward to the "big fix" that SlySoft James has posted about. I really like CloneDVD mobile and once this audio thing is worked out, I'll be really happy.
