I know that the player.swf file in the 5.3 upgrade package can be renamed and used to replace the jw-player-5.0.swf. This does cure the seek bar problem, but disables the ability to play video in the player.
I'd like to figure out how to properly integrate the rest of the files in the package to achive full upgrade integration into Subsonic.
If anyone has any ideas on how to integrate jwplayer.js, swfobject.js, and yt.swf, it's quite possible that this would improve video playback.
