Audio sync issues going from dvd to mpeg1

[nerys]

this is not a HUGE deal as its not all that common (maybe 1 in 15 dvd's do this)

I did a search but nothing specific to my issue popped up

here is what I am doing

I rip with either dvd decrypter or dvd shrink (no compression) it matters not which I use

then I strip it with dvd2avi default settings nothing changed

then I load this up in tmpgenc plus 2.524 and let it do its thing (project wizard defsult vcd nothing special done)

the audio on some discs is out of sync with the video

right now I have a rather tedious way of fixing this :-)

I find a 30-60 second portion of the movie where lots of larges mouths are moving and I convert that as a base point

I then SHIFT the audio in tmpgenc (audio gap correct) -1000 and +1000 and see if its WORSE or BETTER

once I know whuch direction to go I tweak it till it seems insync to me un my test clip and then hit the whole movie with that settings and it usually works just fine

problem is that this takes FOREVER !! it can take upwards of 30 minutes to do this and "get it right" PER movie !!

is there a better way to do thus or better a way to prevent it all together :-)

in the past I would soimetimes hit it with dvdx and 50/50 it would NOT experience the sync issue but its a royal pita to use Slow as you know what and it mpeg1 encoding it not NEARLY as high a quality as tmpgenc's

IE I can watch tmpgenc's mpg's on a 40+ inch tv and they look great dvdx's mpgs artifacts are blaringly apparent :-( plus it only works 50/50 :-)

Suggestions ?

IMO demux the video & audio in the first go. Use the separate streams in TMPGEnc to encode to MPEG. Or. After demuxing convert only the video to MPEG1. Convert the audio to MP2 and then use TMPGEnc MPEG tools option to mux the video and audio streams.

alas that sounds like it would take more time than the current method of fixing it :-(

I'll give it a shot though just for the heck of it to see what happens

"why" would this result in sync and the normal way not ?
