There are a pile of ways to watch your files on your tv.
My set up;
Win7 computer vga hooked to 42" LCD 1080p tv -and- digital audio to SS receiver (THX)
Wireless keyboard and mouse ... Siting in my easy chair.... <<<< that is my remote
U can also hook to a TV with s-video+ (mini to rca/mini to mini)
Or Several other ways do a search it will work...
Now in my kids room the cheapest fix was (and it will work on all TV's)
Buy the cheapest divx DVD player with Usb jack/input just look for .avi support
Got mine for $40 usd
Then I got a 8G flash drive that will hold 6+ hours $10 usd
Total $50 usd
There are wireless Tv's now I don't know how because I have never done it but you could Stream wireless on a network with VLC to the TV. If it is Divx ready has the support.. .avi files
Your TV may be divx ready with a input?
Or the console method. This site is based on computers tho...
Now to answer the ? yes register DIVX In my opinion unless someone says other wise....
