Can't Upload Videos... Help!!!!

I cannot upload videos of any size or type.

I have Dolphin 6.1.6 on a linux server.

I have included the following in my .htaccess

php_value upload_max_filesize 50M
php_value post_max_size 52M
php_value output_buffering on
php_value max_execution_time 3000
php_value max_input_time 3000
php_value memory_limit 128M
php_value mysql.connect_timeout 3000
php_value default_socket_timeout 3000

All these values also reflect in the phpinfo.

But whenever I upload a video I get 'undefined' or 'uploading file error'. I have gone through various forum posts but none of them seem to work. Please Help.

sir, please do not double post your question. you posted this in ray, and that is where it will be answered.

sorry wasnt sure which forum it would be best to post.
