a lot of people i know there audio and video are drifting apart. when a channel first opens the audio and video match perfectly, however after about 2 minutes or less the audio is 30 seconds or so into the future ahead of what you are seeng? changing the channel and then back resets it temporarily but it instantly starts drifting apart right away again.

is there anything i can adjust or change the pids to get a better match, or maybe even something simpler like a buffer setting or disk drive size allocation? is it provider countermeasures? thanks in advance.
