I'm still not getting anywhere with this. although syphon is now working in Catalyst I can't get the render to be any higher than 640x480 even though it's being produced at 1024x768 (using isadora in this case).
Again, any help would be highly appreciated.
it maybe worth mentioning that i didn't get the interactive element to work in quartz using the kineme core plugin preferences within quartz composer but only using this command line in terminal:
defaults write com.apple.QuartzComposer.editor KCSafeModeOverride -dict-add 'CatalystPM 4.40_m466_HD' '( "QCPlugInPatch" )'
(thanks to Bernielomax and Richard for info in the previous quartz threads btw)
