it appears that something is going on with ray. need to check you file permissions on max_upload size. i too ran into this problem some time ago, and there are three areas that need to be modified. in the admin section of the dolphin suite, in the admin section of the ray player, and your php.ini file or .htaccess, the max_upload needs to be set to something higher than 2mb. let me know how you have fared on this and i can help if you are still facing issues.

later,
