thx for the help so far, i circumvented the problem i had by now using a series of still images
with alpha instead of a movie, mixing them together with pix_composite, which works flawless!!!
BUT: i'm want to use different series of pictures(though having more than one movie), which i'm loading
via a random function into the pix_multiimage object, which also works like a charm, but after about
10 times of loading the image sequences again and again i get the error: too many files loaded and pd
won't load any pictures after that, even can't save the patch anymore...i guees this must be a memory
problem, i also found similar post on the internet but no real solution!
my question: is there a possibility to unload the image sequences out of the memory again thus
making space for new?

thx again to all of U
