Note. I am using Mezzmo against my PS3 in my living room perfectly. Couple of file types still will not play (mkv and some dvd preescreen avi file (have no idea what codec they use).

First of, completely remove all your codecs from your computer (most of us have tons of different codec packs installed, ex: divx, xvid, ffdshow and so on).
START => CONTROLPANEL => ADD/REMOVE PROGRAMS
(having trouble removing your codecs, try Codec Sniper)

When you have finished removing everything, reboot your computer.

Download and install:



Now Fire up your Mezzmo copy and try adding video files.. Remember, if they play in Mezzmo, they will play on your PS3, Xbox or other video device..

I have the Lazy man's mkv codecs, but I can't play mkv files with mezzmo. They play okey in win mediaplayer and other players.
If someone have got mkv working with Mezzmo, please let me know in this thread..

Other tips regarding codecs are also welcome in this thread, since the main problem streaming video to other devices will be missing codecs..
