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
CFDictionaryRef m;
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
// to
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.
