Are you using Mk10 from http://vvvv.org/tiki-index.php?page=catweasel±+KittyLitter
I did rework it so it should work with beta9 onwards.
I’ll check it out on another machine and check for you!
Just checked on an nvidia it seems fine, ATI the patch doedsnt load, I have a feeling that deleting the renderer and creating a new one would help here ( if I could open the patch on that machine!) as I’ve had annomilies with different brands of gfx card before.!
But if you getting a black screen the renderer sounds fine. (I get a grey on ATi)
If its the version from the link above then I dont know whats wrong!
Are you dragging the folder onto the iobox or just a file?
If you drag a folder then click thumbs they should appear after a while, then clicking on a channel preview and selecting a thumb nail should play it.!
hmmm
