Right now I use -cache 1048576 (this seems to be the maximum), but I have 4GB of RAM so I could really load almost any movie into it (my usage hardly goes beyond 500MB), but with -cache it doesn't seem to be possible. Or is it possible to increase the cache?

Ok, so looks like I have something wrong in my memory. I'll then do it with the tmpfs

Why I want this? Because if all my laptop does is playing a movie, the harddrive can go to sleep, because it doesn't do anything. Saves a lot of power.

Thanks guys
