I know it's been asked on other threads around here but nobody has found a way to do it yet.

I have seen an Apple retail screen saver that does just that but it's embedded in a special AppleTV disk image that has been made for demo purposes and that doesn't let you sync ans has some drawbacks.

So my question is : would it be possible to write a screen saver (some of the screen savers around do use a movie file for effects) that would let us use a movie file of our choice and that would loop it ?

If some of the master coders that write those nice screen savers could look at this problem it would make many guys really happy !
