Dang...great topic =) I think firstly you have to logically define 'different TVs' from the get go....I think nowadays, that means anything with a HDMI in port?
I think the device you're sort of looking for, would be a 'commercial interface set top box'...a LG or such and similar ..there'd be some device out there like this to fit your specific needs.
I probably wonder if there's an android app out there that lets you do the same thing on domestic grade android based media player/stb devices.... google 'android video presentation apps'
