>> "How do you take fullscreen pics in replay zoom mode. You can't pause it..."
You can pause it, by pressing Ctrl-Y, IF you've typed "gold" during an offline race prior to entering the replay screen. You can take sceenshots too, IF you've typed "gold" during an offline race prior to entering the replay screen. You can do both things even if you load a saved replay from a different track than the one you've just run.
>> "Many screen capture utilities (for unknown reason) dont work in full screen and with hardware acceleration"
Don't use them. MTM2 writes full screen hardware accelerated screenshots to disk all by itself, in any mode, guaranteed. After you've typed "gold" during an offline race of course.
