your tv has to be dlna capable. if it is a newer, high end smart tv then it may be. if not, then i think you're out of luck. to be honest, i know little about dlna, except that any dlna capable device on the same wifi network should be able to communicate with each other, once they are all properly set up (ie. you cans stream from phone to tv, or upload/download files to pc wirelessly from phone, or stream from pc to phone or tv, etc, etc). google "dlna razr" and see if you have any luck.....but first find out if your tv is dlna capable.
Another method if your tv isn't DLNA compatible is to connect a Blueray dvd like I did that had DLNA support, I have a Sony blueray and DLNA works incredible.
All you have to do is connect all the devices to a wifi router and then when you open the stock player on your phone it will give you a option to switch the player and your blueray player will show in the list, select it from list and it will be transferred automatically to the TV...
Also you can set a Windows 7 PC to share the files with player and then you can play movies and music from your PC in another area of the house.
You may also like to try iMediaShare also. I prefer it over the stock app and it gives you free videos to stream..
