Hmm,. I grep'd my log for that, and it is also returning150. So, I
looked in videoout_quartz.cpp, and it looks like 150 is the value it
uses if it doesn't get a valid refresh rate:
// Find the refresh rate of our screen
m = CGDisplayCurrentMode(data->screen);
data->refreshRate = get_float_CF(m, kCGDisplayRefreshRate);
if (data->refreshRate == 0.0) // LCD display?
data->refreshRate = 150.0; // Divisible by 25Hz and 30Hz
minimise AV sync waiting
I'm not sure how that effects playback, but it seems to be the
expected behavior for LCDs, and playback is okay on mine. So, I would
guess this is not the issue.
