Hallo!
This seems like more than a coincidence. Any ideas what going on here?? I'm running Pd version 0.39-1test1 and GEM: ver: 0.90.
I recompiled it now (also with the new yuv conversion by jamie) ... must have been some version conflicts ...
you can find the binaries here: http://grh.mur.at/software/gem2pdp_bin.tar.gz
