Hi,

just recheck follow variables:

safe_mode
memory_limit
max_execution_time
post_max_size
upload_max_filesize

of your server, seems it can`t accept big files :)

and recheck access for writing in
ray\modules\movie\files
and
ray\modules\music\files
folders (chmod 777)
and
chmod 777 ray\modules\global\app\ffmpeg.exe

Regards
