Is slingbox still in business?
UPDATE - I downloaded buy accident the software update for the sling player (which did not work since I removed a faster video card) I used the web browser to view slingbox last year. (I only use it a few times durning the summer) Updating the Slingplayer and then adding the Firefox plugin BOTH the Slingplayer (without the faster video card) and the Web browser version seem to work. I'll keep my fingers crossed and hope for the best.
