I prefer the Voyager drivers, even though they're more expensive.  The Apple
drivers are, in my opinion, TOO modularized,  There's a separate XCMD for each
command (videoplay, videosearch, etc.), a set of player-specific drivers, and
the set of serial commands from the HyperTalk Serial Toolkit.  Each command
goes through quite a few layers of XCMD calls before it gets to the player.

Voyager's set has only two commands (video and vidControl) and a set of
player-specific drivers, so they are simpler and faster than Apple's.  Also,
(and the main reason I switched from Apple's drivers to Voyager's) Apple's
drivers don't work very well in SuperCard.
