Is Notch matrix the default matrix from the KDVD template?
 

On the KDVD sample files, it said it was encoded with "Notch" matrix. Is "Notch" matrix the default matrix from the KDVD template? I made some KDVD video without any filters and the quality is excellent but the edge on fast moving objects had "combing" effect which I did not see on the KDVD sample. Is there any tricks I missed? Thanks in advance for the help.

Yes indeed.
The Notch is the KVCD/KDVD matrix.
As for combing effect it most certainly has something to do with your sources being interlaced.
Are you living in PAL land or NTSC land?
Cheers

I am living in the U.S. Both my kvcd and kdvd had combing effects but the picture qualities are very good. I did not see any combing effect on the sample kdvd files and the objects were moving fast in the sample.
