Does anyone have experience with using the audio delay capability that some AVR's provide? My Yamaha can delay all of the audio channels by 0-160 msec. The manual states that the intent of this is to enable syncing of the audio to the video, and that it is typically useful for LCD screens, that apparently have some delay time associated with the video.
My TV is a rear-projection (CRT-based) Mitsubishi HDTV, but every once in a while I am watching a TV program where the sound doesn't seem to be in sync with the video. But to be honest, I can't even tell if it is video lagging behind audio, or audio lagging behind video. It just seems slightly "not together". I've only noticed it while watching an HDTV show, where the video and audio are coming from a HDTV-capable cable box. Also, in case this makes a difference, I'm not using the video-switching capability of my receiver. The component video from the cable box goes direct to the TV, as does the stereo audio. In this instance, my receiver is getting the audio from the monitor-out jacks of the TV. (I do it this way so that I can watch the analog cable channels directly from the cable to the TV, bypassing the cable box, but the audio to the receiver is always from one place - the TV's monitor outputs.)
Is there a trick or special technique for time-aligning the signals, or does it just boil down to trial and error? Is there a certain kind of source material that lends itself to doing the time alignment? Based on my set-up, should I even be having this issue?
