I have tried the most recent version of Pd extended for os x on a ppc from the autobuilds and it looks like pdp_qt and pdp_yqt still give the unsupported video codec error. I have tried with different codecs but I still get the error. Does someone know of a particular one that has worked? This build loaded up pdp and pidip which I have not got to load up before so things are looking good. Thanks, Alain
