I just tested today's SVN snapshot and can elaborate a bit on the current problem and driver correlation. Like Matthew, I started with NVidia 1.0-8178 drivers. I enabled OpenGL vsync. No problem with NTSC programs, but ATSC programs (1920x1080i in particular) exhibited bad stuttering (1/3 second video+audio, 1/3 second pause, 1/3 second video+audio, etc.) I backed the NVidia drivers down to 1.0-7676 (changing nothing else), and with OpenGL vsync still enabled, I got 2-5 stutters at the beginning of each channel change to a 1920x1080i ATSC program, but then it stabilized and was fine (no more skips/pauses). Note: enabling Twinview (two DACS: #1=CRT, #2=TV) on 7676 causes the same problem as seen with 8178. Presumably the OpenGL extension is the CRT's vsync instead of the TV's. If I swap and make #1=TV and #2=CRT with Twinview, the problem is much less but still not perfect even after the initial stutters. No lock ups however. However, I only tested this briefly. Randall
