This morning the sound was totally messed up on my CBS Morning News broadcast. The voice part of the audio was super low and very squeaky (Technical term!). All my other morning news recordings played just fine. When I tried to watch a recorded CBS episode from months ago...same audio issue! When I tuned to CBS...same audio issue. Reboot did not solve the issue. Switching the audio from Dolby to PCM solved the issue...but of course, I didn't have a Dolby Digital signal. (I did enjoy hearing the TiVo "Bloops" though!) I turned the Dolby back on and decided to go thru all the channels. As I did so, the audio on the CBS channel went back to normal. I checked my previous CBS recordings: All normal. Any idea what took place in my TiVo World?
