is there a descent way to convert a 720x576x25fps xsvcd mpeg2 to 720x480 ntsc xsvcd with avisynth? i would just leave it alone but my dvd player cant handle 576 lines. i thought about doing ivtc to make it 23.976 but the problem is it will take it to 20fps rather then 23. would i need to change the framerate to 2997 1st, then put the greedyhma string, or would that just really screw things up? example:

LoadPlugin("C:\Capturing and Encoding\SVCD\GreedyHMA\GreedyHMA.dll")
LoadPlugin("C:\Capturing and Encoding\SVCD\mpeg2dec\mpeg2dec.dll")
Video = mpeg2source("C:\Documents and Settings\Bill Smithy\Desktop\701_d2v.d2v")
Audio = WAVSource("C:\_ftproot\0701.wav")
AudioDub(Video,Audio)
DelayAudio(0)
BicubicResize(720,480,0,.75)
ChangeFPS(29.97)
GreedyHMA(0, 0, 4, 0, 1, 0, 0, 0)

any help greatly appreachiated..
