@ mascot,
Well, I am using .mkv's with 24p and NTSC from DVD and it works fine.
Only sometimes when stopping one 24p movie and starting another right away it does not change. However, then when stopping and restarting the movie it works fine.
I assume it has something to do with MP 1.1. I already tried MP 1.1 and had several issues that made change back to MP 1.0.2. As I have no problem with stability and recording, dynamic refresh rate change etc. work fine I don't see an advantage (for me) to use MP 1.1 until a final release is out.
sometimes also the movie files are encoded in a weird way, so don't expect that it will work for all types. (well, for those I have it does at least).
Maybe a last statement: If it really bothers you a lot that refresh rate changer does not work - change to MP 1.0.2 if this is an option.
I got it working now.
I use 1.1 beta because I want DXVA with subtitles. If someone could tell me how to inplement the mpc-hc subtitle generator into 1.0.2. I would be happy to go back to stable 1.0.2.
