yes, i figured out, alpha is not working with gem_filmQT4L.so.
i tried Gmerlin. remember that some time ago it was segfaulting in Gem, when loading video, but later i was using gmerlin with mjpeg without any problems. gmerlin is still working with mjpeg, but this with pnga is segfaulting, then loading video.
i tested more machines with same gmerlin-avdec, Gem, kernel, but Pd version differs having different behaviour.
gmerlin-avdecoder 1.2.0-2 GEM: ver: 0.93.git 374f713 Pd 0.45.0test kernel 3.9.3-1-ARCH

on the other machine with Pd 0.44.3test loading video eats all my ram resulting freeze, but nothing in backtrace.
should i fill this in bug report?

It is working perfectly here on Ubuntu 13.04, Pd 0.44.3 and Gem 0.93.git 374f713 (with gmerlin backend). Have you tried to force order with [gemhead 50] for your movie and [gemhead 45] for your background ? ++
