Hidden Cinema 24Hz support on TV

So I finally also got this working, but it took some fiddling

First it didn't happen anything more then the notify popup. No refreshrate change.
I then read that I should populate the custom settings in the Nvidia Control panel with the settings my TV support.
I did and then it started to blank the screen and changed something but ... it didn't work anyhow, or I got black screen and no movie was playing (trying 24hz).

Then I did batch files with the string for Nvidia Grahics (example on the first page of this thread) and put the path in the actions row. Now it work as it should and I'm really happy with this function.

I have some questions though:
Is the API call from inside MP very different from the command string I now have in the batchfile? Even if it works now it would be great to have a technical explenation what is going on and why this is a PITA to get working for many people.
F.e. Why should the two major graphic processor company choose to have the dreaded device reset to change the refresh rate when it's not needed? Powerstrip and 12noon doesn't need it and it always work, no?

Now to the strange part in my research in this matter, and an interresting one:
I thought my Panasonic TH42PX80 plasma wasn't able to play 24Hz Cinema because I can't choose it in the Nvidia Panel and the users manual only says 50hz and 60hz.
I have lately discovered, when fiddling with Eventghost, that there was a setting of the refreshrate to 24hz. I tried and it worked and from now on the Starship Enterprise runs without judder on my Startrek Voyager movies.
I have now also read from a review om my TV that it plays Cinema movies well. Strange that the users manual doesn't tell me anything about it. Is this common?

How does the TV refresh when you use 24hz? It must be some multiple higher refresh rate on the screen to not have flicker, right?
Can anyone explain how the plasma screen is updated when it plays 24i and when it plays 24p? Can a screen refresh interlaced when the program source is progressive?

Many questions but I think some of them is of interrest for a few more then me.
