i know this topic has been probaly beaten to death but after a through search i cannot find the answer to my problem. i have 4 mpegs i had to download via a p2p connection as i was missing them from completing a full season, they play find on my pc but when authored and burned they lose audio sync about 5 minutes in. i have tried this using both tmpegenc dvd author and dvd lab. i have tried demultiplexing and then multiplexing them back again. now i have been fortunate enough not to have any audio sync issues with anyhting i have done . my thought is probaly due to the fact the mpeg i downloaded is at 44100 hz and both tmpegenc and dvd lab both require them to be at 48000hz to be dvd compliant i feel maybe this is where my sync issues are coming into play. i am still exploring the tmpgenc dvd author program itself so i just noticed the the program automatically defaulted to rencode the audio at a birate of 224kbps,48000 hz. all my extracted dtivo "mpegs " are at 192kbps,48000 hz. just an educated guess on my part like i said this is a new probelm to me. if anyone has some experience with this please let me know and thanx for all ahead of time
