New MeGUI con't open GraphEdit's GRF File?

[cscxk]

I use MeGui's "AviSynth script creator" to creat my avs file.But Now,i con't use it open graphedit's grf files.When i open it, i get a error like this:
http://forum.doom9.org/attachment.php?attachmentid=6626&stc=1&d=1168035610
And i create a sample avs file,like this:
DirectShowSource("4.grf", fps=25, audio=false)
and use MeGui's "AviSynth script creator" open it ,all is right.

why? i need any other setting?

i get this too, dont know why :(

what are the dimensions of your video? both width and height should be divisible by two-else, avisynth may not be able to load the file. if you can force the decoder not to use YV12 color space-it may work
above problem crops up with quite a few vids from youtube.

the video dimensions are devisable by 2. Avisynth can load the file fine, i normally make my own script to use .GRF files as the problem only occurs in MeGUI's make script tool.... weird.
