Finally watched the 10/1/06 "Cold Case" I had recorded on my 622, last night. Found something weird, there were at least three segments of the program, each lasting about 3-4 minutes, where there was no dialogue coming through the sound system (I saw the lips moving, so I know the characters were speaking), however, the background music was audible, as was environmental background noise, like city traffic, horns, etc. I know they put the sound on different tracks, I am wondering if this was a problem from the production studio, CBS, or another 622 audio glitch
