To update JW Player to the newest version, go to
http://www.activeobjects.no/subsonic/fo ... php?t=5977and read the instructions. Read the whole thread as you'll see there is the long way and the short way. I use the method I suggested as it seemed to be less time consuming. IF I want to know what version of the player I'm running, I'll just fo a right click on the installed player and it will tell me what version it is.
I just downloaded JW 5.X, extract player.swf, rename it to the current name in the subsonic/jetty/xxxx/webapp/flash folder and replace the original file. Rename JW Player 5.4 to Old JW Player 5.4. then drop player.swf into the directory and rename it to JW Player 5.4 when you're done it'll be named 5.4 but if you right click on it in SS you'll se that it's really 5.X
