OK, but has there been a definite "no, forget direct video and 2D acceleration" statement from Sony/nVidia/YDL? It seems like this is the current state of affairs, but not necessarily the end of the story. > It should be possible for applications to use the SPE's to accelerate > rendering to this internal frame buffer, but that will likely have to > be done one app at a time.

As clever as this is, it's kind of silly to go that route considering the graphics device is right there on the motherboard. If I could pick one program to get that acceleration, though, it would be mplayer :) Ted _______________________________________________ yellowdog-general mailing list [email protected] http://lists.terrasoftsolutions.com/mailman/listinfo/yellowdog-general HINT: to Google archives, try '<keywords> site:terrasoftsolutions.com'
