I've been trying unccessfully to encode a concert DVD that is encoded as interlaced NTSC @ 29.97 fps. It appears to my eye that the original source was video (not film).

I assume that the KVCD process requires converting to a progressive 23.976 fps format.

So far I've:

1. Ripped the video and audio into vobs using DVD Decrypter.
2. Generated a DVD2AVI project with force film OFF and demux for the audio track.
3. Processed the ac3 files with headach3e to generate a 44.1/160kbs dual channel CBR mp2 file.
4. Encoded the video with TMPGEnc using the KVCD Plus template. Video source is interlaced and output stream is 23.976 fps.
5. Muxed the audio and video using the TMPGEnc simple multiplex tool.

The results have "window blind" artifacts wherever there is rapid movements, such as drum sticks & guitar strumming.

So how should I do this, or is this to be expected?

If the original is a video, 29.97fps interlaced, you have to encode at 29.97fps. Just deinterlace with TMPEG or an AviSynth script and change the frame rate to 29.97 in the template you're using.

When I load the KVCD template and the video file into TMPGEnc the wizard enables the inverse telecine option by default. I assume that I should disable this and enable deinterlace?

Also, which deinterlace option should I choose (there are 16). The default is none, which does not actually perform the deinterlacing!
