Such a beast doesn't exist yet

Most HDTVs lack the ability to play back one or several of those formats unfortunately.

Your best scenario is to either convert to a format that is know to work 99% of the time, or find a cheap media streamer you can keep connected to the HDTV and use USB flash drives to throw up files you need. Even better would be to simply connect to a low end PC/laptop where all files may be played back with free software/codecs.

Let us know if you would like any additional help. I have had luck w/ both Roku & WDTV Live media players, FWIW.
