1. VIDEO: Fix QuickTime regression with mediaTime and dithering …

   Fixes an error when playing a QuickTime video that has a mediaTime set
   on its first edit. This was caused by mediaTime changes in:
   ef184a6
   
   Those changes buffered frames during initialization so that the keyframe
   and other frames don't play instead of the intended start frame that
   mediaTime specifies. My mistake was that decoding isn't allowed during
   VideoDecoder::loadStream(); VideoDecoder::setDitheringPalette() requires
   that no frames have been decoded yet, and at least Director and Mohawk
   call that.
   
   Now the initial mediaTime buffering is delayed until the first decode.
   
   Fixes bug #13479 where certain Myst videos error.
   Fixes the opening movie in the Director game Chop Suey.
