buffering when skipping through movies

[TheDreadPirate]

"Direct stream" = audio transcoding, video is copied unmodified
"Transcode" = video transcoding, audio may or may not also be transcoding
"Remux" = video and audio are copied, unmodified, into a new container
"Direct play" = file sent directly to the client in its original form

My statement about skipping past the point that has already been transcoded is the likely cause. And this is expected. If you skip to a point in the video that HAS already been transcoded, it should be near instantaneous.
