How to play DivX, Xvid, AVI, MP4 files on your PC or TV?

Well, you can try to do this the hard way by converting the MP4 based
formats to mpeg 2 or vob and package/burn them into DVD discs.  This can
be very time consuming and you still have to use physical discs to be
able to play them on your DVD player.

There are tons of companies with templated websites :) that try to sell
their video conversion software.  I'm surprised they are still in business.

There is much easier and simpler solution to playback of Internet video
files.  You have to get a Media Player hardware device.  You can use ebay to get
no name one for $20-$30, or get a brand name box for about $80-$100.

I bought "Western Digital TV Live" Media Player box.  It comes with 2 USB ports (stick and
wireless or external hardrive) and RJ45 for a wired network connection, HDMI, RCA, component
video and optical output.  Pretty much everything you could possibly want.

It plays any video format that you can download from the Internet :-)  It can play YouTube videos as well.

Amazing box.  It plays movies straight from your network drive or share.  I had a spare Linux box lying around so I used it to setup a network share.  If you want to be fancy, you can get a Virtual Private Server or as some call it a vps and setup your videos there.  My brother in-law got one and he swears by it. He can access his videos from anywhere.  The VPS is like a standalone Linux box, you have full control over it. But for such a setup you probably need a cable Internet with tons of bandwidth.

No more conversion and burning.  Besides do you remember what happens to all those
DVD discs once they have been watched a couple of times. 

If you want to play MP4 encoded files on PC, download "K-Lite Mega Codec Pack 5.9.0".
It comes with a player that will play anything under the sun.
