I've decided to rip all of my old RC1 Avengers DVDs to MKV/AVC/AC3 for DLNA. Ripping itself goes fine, but I've come across an encoding issue I can't solve: By stepping through the ripped video frame by frame I thought enabling Vidcoder's (standard) detelecine filter might be appropriate. And I set a fixed frame rate of 23,976. The resulting video runs smoothly but still has combing artifacts. Enabling the (standard) decombing filter as well gives a better result, but from what I've read so far the detelecine filter alone is supposed to get rid of all combing.
If anybody would like to have a go at what's going wrong, I've upload a short chapter in original format (85MB) HERE.
Hints highly appreciated,

I don't use Vidcoder and so have no idea why 'detelecine' doesn't work for your source. I had a look at the sample and it easily and perfectly IVTC's using AviSynth's TIVTC filter. So, if you can't get it sorted out you could use an AviSynth script in a different encoding program.

Maybe someone else will come along with the answer to your question.
In the meantime I dug out the old Staxrip, installed its latest version and TIVTC filter and gave it a try. The result with the filter's defaults tfm() and tdecimate() looks pretty good at first sight.
The resulting video has a cfr of 23.976, which is just what I expected. Can we rely on TIVTC to discard just the right number of frames to reduce the frame rate to 23.976? Or is there a general parameter for tdecimate to make sure the encoded video will have the correct cfr?

So yes, you can rely on tdecimate to output 23.976fps.
