I'm just starting out using PDP and PiDiP on a Mac and I'm having some trouble getting anything to display.
When I send a video to pdp_glx and bang it to play, I get this message in the Pd window repeatedly:
pdp_glx: autocreate window
pdp_xdisplay_new: can't open display :0
pdp_glx: cant open display :0
Eventually a blank X11 window opens with bash-3.2$, and the audio of the video plays, but the video is nowhere to be found.
I'm using a fresh install of Pd-extended-0.42.5 on Snow Leopard, and X11 is definitely installed.
