Web player

We are working on a digital signage solution and it will run on mozilla browser.

It will be running the following formats :

FLV
MPEG
MP3
FLV
SWF
WMV

We are currently using Windows Media pLayer for it but the problem the configuration settings for the player doesnt work at all in Firefox such as hiding the controls , muting the videos and so on.

Can anyone suggest of how to achieve this in FF or alternatively suggest a player for web.

You should switch. JW Player is a typical player used by many site. I would
also suggest to look into the HTML5 way.
