customisable player.
You can choose a player in User Preferences -> File Paths. You can
choose a plan custom command line, otherwise there are presets available
for the Blender 2.4 player or DJV (where it will give it the correct filename,
fps, etc on the command line). So for example if you have a Blender 2.4
version installed, you can enter the path to the blender 2.4 executable,
and the playback will work just like before.
Any info on other frame players (FrameCycler? pdplayer?) and their
command line settings could be useful for adding some more presets too,
if anyone knows of them.
It's available in Render->Play Rendered Animation (Ctrl F11)
