Avisynth open failure in GordianKnot

[zeronegative]

After upgrading GordianKnot to 0.28.4 I can't perform IVTC anymore. After I check 'Inverse Telecine' and then 'save & encode' I get the following warning:

VirtualDub Error
Avisynth open failure:
Telecide: YUY2 data only
(C:\...)

In DVD2AVI (1.77.3) I can only choose RGB or YUV, neither of them making the error go away. What now?

look here:

to sum up: new decomb cannot IVTC in YV12 yet...
(I rushed too much with it, but you can replace decomb.dll with an old one and it will work...)

Or you can add ConvertToYUY2() to the script (preferably just below the Mpeg2Source line) and continue to use the newer Decomb. But you may run into problems later if you use any filters that demand the YV12 colorspace. One version of MipSmooth does, but I don't know about any others.

make that ConvertToYUY2(interlaced=true) ...

Well, right now I'm going for the previous Decomb version and everything's working out fine. Is there any reason for using the newer Decomb with the ConvertToYUY2 trick instead of using the older Decomb?
