I am using JW Player ...I am using JW Player version 4.3.132 with a playlist including flv and mp4 on my server and flv from youtube.
Each video in the playlist also has an associated jpg image.
All was working well untill Flash Player auto-updated to version 10 (10,0,12,36).
flv and mp4 hosted on my server will now not load into player from playlist nor will their jpg image files.
Youtube videos continue to to load and play, though their jpg image files will not load into the player when they are selected from the playlist.
This behavior is consistent whether I use Firefox 3 /w Flash Player 10 or IE7 w/ Flash player 10.
All file paths on the xml file are absolute (I will paste example), and all files are on the production server.
If I test locally (by this I mean opening the html page; file:///C:/......) all videos and images load as expected.
The player is at;

Sample xml is;

It seems the problem is a Plash Player 10 security problem, but the player will need to operate in this environment, so I guess a patch is needed.

Add the www and ou won't run afoul of the same-domain security restriction:
<image>http://<strong>www.</strong>fishrock.com.au/video-gallery/thumbs/wobbegong-feeding.jpg</image>You MUST use the EXACT same domain! (Or upgrade to a player that doesn't have this problem.)
