Hi, I'm here again with a new sync issue, which I can't solve, pls help.

The purpose is to use the PAL DVD audio on a 24000/1001 BD video source.
But something is weird with the DVD, it has 6 interlaced frames plus maybe 19 normal frames.
I just have to fix the DVD frames in order to match with the BD.

but how?

using TFM(), fixes the interlaced frames but produces a doubled frame every 24 or 25 frames.
so i think maybe I have to add another command. which one?

TFM().TDecimate() is not working good, some frames are missing.-
help pls-
