I have a PAl avi @ 576x320, 25fps (40000u.s.), xvid mpeg-4 codec, 48000hz/2-ch stereo (according to gspot and vdub) and am trying to convert it to NTSC DVD @ 23.976fps (then applying 3:2 pulldown to 29.976fps to watch on NTSC TV).
'
I've attempted atleast 10x, using TMPGEnc Plus and avisynth frameserving to CCE2.50, and each time the damned result plays in SLOW MOTION in PowerDVD and WMP9.0.. wtheck!?? Has anyone experienced the same or advise..??

Avisynth is simple script into CCE 2.50:

AviSource("C:\PATH TO\source.avi")
LanczosResize(720,480)
AssumeFPS(23.976, true)
AddAudio()

And here's what I'm doing with TMPG Plus:

1. open TMPGEnc and close wizard
2. import avi as video source and audio automatically loads as audio source
3. load NTSC DVD template and Unlock settings
4. Source = 1:1 VGA, non-interlace (progressive), topfield first (I've also tried soure = 4:3 625 PAL)
5. resize to 720x480 at 23.976fps, 3:2 pulldown playback, ~4000 CB, 'do not framerate conversion', 4:3 display (keep aspect ratio)

This is very frustrating... Would appreciate some help.
