Advertisements I've been experiencing 1 second (or less) audio drops on FX HD (channel 231 - WOW in Naperville, IL zipcode 60565) for many months. The problem repeats at intervals between a few seconds and perhaps a couple of minutes. I don't experience this on any other channels. I assumed it was a broadcast problem even though WOW said they've had no reports of this problem. The problem exists when I watch a recorded FX show as well. I recently had both CableCARDs replaced (one went out and both were exchanged for a multi-stream card which I later found out this TiVo does not support). I have two different single-stream cards now and the problem still exists. I spent some time today diagnosing the problem and discovered the dropouts are not consistent when I rewind and watch the same scene from a recording! I also discovered this problem doesn't exist with the TiVo's RCA L/R audio outputs. The TiVo has an optical connection to an Onkyo TX-DS898 AV receiver. I've tried different decoding settings (TV Logic, ProLogic II, etc.) on the Onkyo and it doesn't help. The TiVo's Dolby Digital setting is "Dolby Digital" which I thought was the right setting since my receiver can decode the signal. However, I just changed the TiVo to "Dolby Digital to PCM" and the problem is gone! Why would this problem only affect this single channel? Does this mean FX HD is encoding the audio signal differently than other stations? Is TiVo Dolby Digital or Dolby Digital to PCM the right setting? What am I giving up if it's set to PCM? I still get the TiVo "beep" but I think that's because I have one set of its RCA audio outputs connected to the Onkyo. I'm not certain, but it's possible that set to PCM the audio is slightly out of sync with video on this channel or possibly all channels. I'm having trouble telling for sure. Thanks to anyone that can help!
