[Win10 64; 099 13460] True Length not real length

Hi Team, as i already talked to Ben on Facebook here a toe reproducing my error:

I want to set the loop-position of a movie-file-in framewise. For this i use the info chop to get the true length and substract my difference.
The Problem appears when using movie files wich run in another Framerate then the project. So a 30 FPS movie will end half way in. a 25FPS movie will end 2,4 times faster (60/25) etc.
I can counter this behavior by taking the TD-FPS, divide them by the Movie FPS and multiply this with ‘true_length’.

You can use op(‘moviefilein’).numSeconds and op(‘moviefilein’).rate to get real data from your movie.
