First I think you shouldn't be using the mms: protocol - the player 
software uses that, and you are just wanting to detect if the file exists.

To find out what causes the problem you shouldn't suppress the errors 
:-) so try this without the '@'.

I think that with PHP5 it is possible to use some URL wrappers with 
these too.

I'd probably do this with curl, see http://php.net/curl where you'll 
find some examples too. Others might prefer socket functions:
