Ok I have tried lots and lots of things such as downloading the sync patch (thanks for telling me to do so) and changing my Tmpgenc to the new version. I always use v-dub for sound before I encode using the normal settings in tmpgenc(follow the guidelines) but still after weeks and weeks I have still the same problem.

Movies downloaded as mpeg and then burned(with nero) plays fine on my dvd so its not my cd-r or my dvd player.

But any movie I encode then I always have a few time during the movie some slow images and or sound sync. After the first few minutes it happens maybe every 7-8 minutes or so afterwards. I tried many things such as changing the settings in tmpgenc and burning at different speed but since mpeg downloaded form p2p programs plays fine and are burned fine I do then beleive its tmpgenc that is my problem.

ANYONE WHO MANAGES TO SOLVE THIS MATTER HELP ME!!!
