20 milliseconds delay

Hi, friends. I use Premiere to synchronize audio and video (.avi) and I love this software, but there's a thing bothering me. I noted the sometimes a frame suffers a time variation of 20 milliseconds. The difference is always 20 milliseconds! For example: Before to repair the audio synchronization, I select a frame that begins at 00:03:11:43200. After I synchronize that and several others parts, I return to "frame 00:03:11:43200" in order to see it again, but, now, the same frame begins at 00:03:11:41200! I would like to know why it happens and if is there a way to avoid that variation, since it destroys the confidence on lipsync. Should I use mp4 intead avi?

Thank you very much in advance.

It looks like you are working with Audio units, there is a good chance Premiere is going to the nearest viseo frame.

I don't understand it. When I revisit the same frame several times as I continue fixing other parts, it can return to normal or no. I would like to know a way to stop it, since I can't be sure about the timing. If I set some audio 5 miliseconds after the mouth opens, for example, and the same frame now starts 20 miliseconds earlier, sound will be produced 15 miliseconds before the mouth opening. And, sometimes, it returns to original timing when I revisit it. I have no confidence to do the job anymore. Do you have any solution?
