Audio sync problems regarding MPEG 2 to MPEG 1

[Jaybo955]

Hello, I'm fairly new to converting mpeg2 to mpeg1, but it is vital that I do it in order for the video to play on my DVD player (which lacks SVCD playback). I've tried burning the VCD after converting it with TMPGEnc, and the audio was too fast for the video. Next, I tried first converting the audio to WAV, thinking that would fix things, but the program I was using (dbpoweramp8) would freeze every time just before it got to 50 percent completion. Obviously, virtualdub won't allow me to extract and convert the audio seperately, because it doesn't support mpeg2.

Please help, because I'm almost to my wits' end!

Is your MPEG-2 coming from a capture card? A software MPEG-2 encoder? What?

Using a Creative Videoblaster VCR, I do roughly the follwing:
1) Run the MPEG-2 through PVAStrumento.exe to fix sync errors from possibly glitchy captures. (this step not always needed)
2) Save a project file using DVD2AVI (.d2v and .mpa output)
3) Convert the .mpa audio file to .wav with MPA2WAV.exe
4) Write a short Avisynth program to feed the video to VirtualDub
Example:
LoadPlugin("C:\software\MPEG2DEC.dll")
LoadPlugin("C:\software\Avisynth_Spatial.dll")
mpeg2source("C:\send to mandy\<filename>.d2v")
TemporalSmoother(3)
SpatialSoftenMMX(1,4,6,false,false,4,4,6,8)
5) Open the Avisynth file in VirtualDub and add the audio as a .wav file -- applying any audio offset if necessary. Under FRAME RATE, make audio and video duration match.
6) Frameserve to TMPGEnc.

In step 4 you would also want to use an inverse telecine plugin to convert an interlaced 29.97fps video to a 23.976 fps non-interlaced video. There are now at least 4 of these... GreedyHMA seems to work the best for me at this time, but others may soon outperform GreedyHMA.
