24 Hz VS 23.976 Hz
Received mine, and am overall happy with it. In the PC's display mode options, it lists both 24 Hz and 23 Hz. The latter is usually the OS's shorthand for 23.976, and it does appear to accept it as a mode.
That said, when playing back 23.976 FPS videos in either mode, there is some pretty severe tearing. This leads me to believe that there is in fact not a true 23.976 mode within the Optoma, and that it's simply going back to 24 FPS. ReClock is able to bludgeon the playback into a mostly tear-free state, but I just wanted to make sure that I wasn't missing something, and if I could attain true 23.976. On my Panasonic LCD TV, it took some fidgeting on the PC end before it would finally cooperate with the TV to do such.
