I'm using pix_movie to play .dv movies by asking for each frame in turn, so that I can scrub, pause etc with all machines in sync. It works well, except for the intermittent series of hesitations I assume are either dropped or late frames. To debug this I switched to using a single machine, no network connections and tested using [auto 1( instead of frame-by-frame - only 1 clip playing in this simple setup. Then tried different codecs - H264, PhotoJPEG each 576x720 and 1024x768. The MacMini is connected to the 1024x768 projector via a short DVI cable. The GEM window is set to fullscreen, frame rate 25. There was a slight improvement with the [EMAIL PROTECTED] but the problem was still there. Quicktime could play all the movies at fullscreen smoothly. I have some other MacMinis - PPC and intel - coming soon so I'll test these and try higher framerates for GEM. The Intel ones have just been used with Isadora in a similar way and apparently had the same issue. The hesitation is only very noticeable on video with fast moving, high contrast scenes - but it is obvious then. Pity about the shader performance - I was planning to use Minis for a more complex setup with masks and some colour correction but I guess I'll need to go with bigger boxes and better graphics cards (probably similar $$), or try to find some old G4 Minis.
