Hi,
i tried to backup THE LORD OF THE RINGS DISC2 and everything seemed ok on PC. (i was following tutorials from here) But when i tried it on my settop player then i was suprised. There was lot of "blinking" and the entire video was jerky. It is not my first DVD but it is first which is doing this. (DISC1 works perfect)
I suppose that i did something wrong in CCE setting but i don't know what. Can someone help me?

Contrary to the obvious, the upper field first checkbox has nothing to do with setting the TFF (top field first) flag. In fact, Cinemacraft encodes with the TFF flag ON regardless of any setting. Enabling upper field first in reality inverts the field order by shifting the entire image up 1 pixel....even scanlines become odd and vice-versa
This causes order reversal or mismatch problems if your source is anything other than top-first as indicated on the chart. The solution is to pre-empt Cinemacraft from altering anything (upper field first OFF) and set the TFF flag with Pulldown at a later stage. Progressive material (IVTC/forced film or PAL standard telecine) is unaffected other than being shifted 1 pixel and thwarting attempts to letterbox on 16x16 macroblock boundaries

ah it seems like i missed something important. And i forgot to tell that my disc is PAL. (if it is important)
And i thought pulldown isn't really nescesary for PAl conversion. I have 25fps during all conversion (i hope).
I am dunno and maybe i didn't understand it correctly. You say to encode with cce not using top first and then use pulldown to set TFF.
Ok i'll try it.
Thanks a lot
