Hi there J bz,
have just seen your thread over here and i´m sort of having a similar problem,
i´m trying to play 2 videos simultaneously on a Windows machine.
But whenever i try to make it fullscreen it will decrease framerate and apparently
uses a lot o cpu processing... i think a have problems with encoders on my windows
machine.
which encoder are you using ??
thanx a lot,
Fernando.

Aaah, thank you indeed.
I checked the original on a mac today, and it sort of worked, no crashing.
Will report back after more testing.
Not the first time you have waded in and lent a hand, much appreciated.

I don't know which video codec is better on Windows for your patch.

send variables in local.
In your subpatch you use '$0-frame' to send the number of frame of your
movies. The problem is all your receive $0-frame will receive the value
of the 3 movies.
So i remove these objects (heve a look inside the subpatch).
