IIRC, I believe the issue is that the PVR-350 framebuffer itself is not fast enough to handle full-framerate video that bypasses the MPEG-2; it has decoder.

Yes, definitely that, since the -350's framebuffer does not provide hardware 2D scaling (Xv), so the scaling must be done in software. -JAC _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
