Firefox points to MPC. I notice that under the File Types list that dictates what to associate, there is a Plug-Ins... button. When I click that I get a list of a number of filetypes. RAM is NOT among them. What's with that?
Well... RAM is not listed then it's not installed properly with plugin or its not activated.
Re-install real alternative 1.30 and make sure plugin for mozilla/netscape is checked.

I thought of that. That's why I went back and tried IE on it and IE launched RPA just fine
RPA... is an real player authorized third-party Add-in that give you access to functions like a toolbar and buttons.
(Active X add-in likely only works with I.E)
Keep in mind some sites are biased.. You will also notice streaming sites prefer windows media, apple quicktime or only use real media depending on which browser you use (depending on programming code by webmaster.) I tried the Yahoo news site you mentioned. Mine loaded in new window with WMP player plugin and played "Daughter Missing video" just fine.
P.S. if going to quote me... use the QUOTE/reply button that's what it is for.
