Probably because it has to extract the audio, send it to the bluetooth audio chip, from there it probably gets processed again, then it stands in a bloody line to waiting to get blasted one little 0 or 1 at a time through the bluetooth radio, magically finds it's way to your headsets radio, gets magically reassembled (btw if one of those 0 or 1's is missing a search party is called in), by a much slower chip I might add, from there converted into a analog signal sent to the drivers in the headset, then into your ears and then your brain has to process it.

 

Wow I am really sorry I was not trying to offend you at all. I was just trying to joke around in obnoxious manner. I honestly I really don't know how bluetooth works, I assume that I left out no less then 42 steps in the process. Also I never intended to imply that you had any sort of mental deficiencies.

Maybe the issue is with the media, have you tried anything with audio encoded in a lower quality?

 

I think it has to do with the computers processor. On my Hero, the audio/video is out of sync, but on my laptop, which has a 2g cpu,
it's all in sync. Maybe it's the memory. My laptop has 4gigs of memory.
