Sound out of sync (just less than a sec)

[Dutch Devil]

I've got a very annoying problem with the vcd's a play on my JVC dvdplayer. The sound of the vcd's is from the beginning out of sync, but just less than a sec. This player supports all cd-r's and cdrw's so that's not the problem. On my pc the vcd plays fine. The movies I convert are all NTSCFILM formats (23,976 fps). I use VirtualDub to split the sound as a wav file from the avi. Then I use Tmpenc to Convert the movie to an mpg file. I use the NTSCFILM template and click the 3:2 pulldown what many people in this forum suggest for NTSCFILM after that I split the file within TMPenc.
i know that a lot of people have problems with NTSCFILM and the out of sync problem but never a clear answer was given for this very frustrating problem SO PLEASE HELP!

Strange. I don't think it has to do with the NTSCFILM, for when I use normal NTSC and I convert the audio to wav and then encode using TMPGEnc I get the exact same problem, the sound starting slightly after the video, very un-watchable. I'm not sure why that is, I'm trying to just encode the video and then multiplex it now, I hope that works...

I've noticed a similiar problem with one of my vcd's. The sound plays in sync on the computer (even on full screen) but when played with the 500W, the sound is very slightly off. How could this happen?

Did anyone ever come up with a solution to this problem? I am having the very same problem (for whatever reason, all of the divx's that I am trying to convert are 23.976 as well). Is the audio sync problem (working on the computer/out of sync on the dvd player) unique somehow to this frame rate? Did anyone have this problem with 23.976fps and not have the problem when trying 29.97fps?

Would really like to know if there is a solution to this one.

I don't know the answer to the problem, but unless your VCD player is quite strange, leave the VCD as a 23.976 fps VCD - don't do the 3:2 pulldown to convert it to 30 fps.

Most players play 24 fps VCDs just fine.

For a VCD - the 3:2 pulldown actually adds redundant frames to your encode (for SVCD, the 3:2 pulldown in the encode mode just adds a flag bit to certain frames, so doesn't change the size of the file).
