Problems using CCE 2.5 SP to convert huffyuv to mpeg2

[baseband]

I have a two hour long, 60GB file captured in HuffyUV (Predict Gradient, Convert to YUY2) on my Athlon XP 1800 running Windows 2000 Pro SP2.

When I try to frameserve with AviSynth, using the following script:
AVISource("f:\1.avi")
Trim(150,35935)
ReduceBy2
ResampleAudio(44100)

I get this error :
Frame Rate 10000000/332897 not supported. Supported frame rates are ..(list of common frame rates).

Loading the .avs file in WMP seems to work fine. Loading the entire avi file into CCE directly gives the same frame rate message with the same numbers. Ditto with other HuffyUV captures. Also, serving the file from VirtualDub yields the same error. A Divx file loaded directly into CCE seemed to load fine without the error message.

Oops, just realized I was reducing the image by the wrong size. I wanted to make an SVCD not a VCD. Unfortunately, I still got the same error with the changed settings. BTW, my capture is 29.97 fps NTSC, 704x480 (yeah I know I should have used 720 for SVCD, but I had originally planned to make this a VCD and changed my mind).
