I don't think this explains no frames; maybe a good bit less, but he should see a frame now and then or this is the result of something else. |in this respect fxtv should be a bit more adaptive -- when switching to |use X11 it should really work one or two frames at a time and try to |synchronize with the server. That's a thought. Though on my system here, I also can't get max frames per second (NTSC = 30fps) on a zoomed TV window in XImages mode, and I don't notice any loss in X server responsiveness with fxtv trying as hard as it can. XFree seems to handle this load gracefully, blocking fxtv when it's got enough images in the queue. Of course this is just a specific instance which doesn't prove it true in general.
