I don't want to turn this post into a debate over the 2 but I believe the market where RTI is pointed towards is not at DIY it is towards integrators that are after a whole solution and MyMovies is a server client based media solution that handles burning and integrates movies and TV Shows perfectly into Media center interface and lets not forget the driver is for media center and if it can not be integrated into the current movie setup in Media center then I think MyMovies is much more likely and currently is being used on more integrated systems as a very client based easy to use system which is what MediaBrowser is not ?
The feedback from customers as this is how I am trying to see all this is that they want a solution that will burn DVD and bluray and auto lookup metadata etc and appear in media center and MyMovies will do all this and act as a standalone burner etc that will import into the standard media center movies section which if Matt can get the standard movies going will still be able to be used but if he cannot then it can be explored further with MyMovies integration.
I just believe the market for these drivers are to integrators and I would not install MediaBrowser on a customers computer as it requires to much user interaction and offers no burning features.
Sorry for the long winded post but Matt I know your time is valuable so it is just my feedback as an integrator to advise as to what I believe is a solution that you will be able to sell a lot.
If it helps as I am sure you have probably seen is
www.vidabox.com their system is only sold to integrators and uses the MyMovies platform as the base for all movie, TV Shows and Music management and I think they were also at Cedia last year in Australia ?
