Someone brought this bug fix to my attention:

If movie contains quotes in name, JavaScript won’t be able to open the file. You must add $movie = htmlentities($movie, ENT_QUOTES); at 64 line in flash.php to fix this bug.

Hopefully this helps anyone who was having this problem.

Happy New Year everyone. Thank you for your continued support of the OSFLV Player.

Throughout 2010, we will continue to improve and debug the player.
