Hi João, Max,
Indeed, the buffers would not solve the problem.
But I was thinking that the patches controlling VLC and quicktime
would provide a solution or a way to find a solution.

But they may give you an idea how to proceed. It's definitely not a good Idea trying to load a long HD movie in a [gemframebuffer] it might even crash gem if the memory on the card is not sufficient.
