I didn't know how to search for this type of problem let alone describe it clearly, but I've noticed the MP4 locals have a gurgling effect in the audio. I did a normal reset, does anybody think a red button reset would help?
Also, just my theory.....turn Native OFF and set TV to 720P or 1080i mode and see if this helps ? It seemed to reduce greatly for me....course I could be going crazy. My guess is if the HR20 controls the upscaling instead of passthrough it may have a better chance to decode/sync audio with video......just a guess though.

I already have native off and I don't have 780p. I have it set to 1080i. Just out of curiosity, why would changing the video resolution improve audio quality?
I'm not saying changing the resolution from 1080i to 720p would do anything on its own. My comment was turning NATIVE OFF and then selecting either 1080i or 720P mode you wish may....and I mean may....have some effect. My crackpot theory is if the HR20 is controlling the resolution generation/scaling to the screen it may also at the same time sync the audio. If it is in passthrough mode (NATIVE ON) then perhaps there is more room for sync and/or audio corruption errors. Think about it....the channels in HD are filming in 1080i or 720P MPEG2 then they go thru encoders to transcode/transrate to MPEG-4......all the time trying to keep audio in check, in step and not corrupted. If there is some pixels on the screen dropped you less likley to noitce than a obvious lip sync problem or audio glitch/noise.

Again....this is just my theory on what might help....no one from D* or Earl has said this....in fact there has been little/no acknowledgement officially I can find on audio having problems. Sure are a heck of alot of threads on the subject though.
