Hello,

Is 60hz just too slow for NTSC + Bob deint?
Or is something lying?

I get this when I try to play back NTSC video
on my LCD TV running 60hz:

2006-04-16 22:54:19.226 OpenGLVideoSync: x,y -> 720, 450
2006-04-16 22:54:20.944 NVP: Timed out waiting for free video buffers.
2006-04-16 22:54:21.338 Using OpenGLVideoSync
2006-04-16 22:54:21.338 Set video sync frame interval to 33366
2006-04-16 22:54:21.338 Video sync method can't support double framerate
(refresh rate too low for bob deint)
2006-04-16 22:54:21.339 Set video sync frame interval to 33366
2006-04-16 22:54:21.342 Using deinterlace method bobdeint
2006-04-16 22:54:21.354 Using audio as timebase
2006-04-16 22:54:21.354 Video timing method: SGI OpenGL
2006-04-16 22:54:21.354 Refresh rate: 16697, frame interval: 33366

16697 > 33366 / 2 

And according to vsync.cpp, that's a problem.
I something lying, or are those numbers correct?
