-// up a video too much, it can't keep up, and rendering stops updating except on

-// use up the data we have, which may not achieve the speed requested, but will

-//
-// A very slow speed, ie 0.00000001x, causes the machine to lock up. (It seems
-// like a busy loop). It gets unresponsive, although its not completely dead.
-//
-// Also our timers are not very accurate (especially for ogg), which becomes
-// evident at low speeds and on Vista. Since other speeds are risky and outside
-// the norms, we think 1/16x to 16x is a safe and useful range for now.
