I used to stream all of my media from my computer to my TV using Windows Media Player 11 when I had Windows XP. It was incredibly easy and straight forward. Then I upgraded to Windows 7 and Windows Media Player 12, and after a lot of finagling, I finally got it to work. Then came the upgrade to 64 bit. Now I can’t get it to work at all and I know I’ve done the exact same steps. In fact, it was working but for some reason it just stopped. I tried the forums and despite the different offers of fixes nothing worked. So I gave up and ran across a free media server called TVersity. Incredibly simple to set up and use. I had it done within ten minutes. Now, along with the video files, the music and photo files that never worked with WMP12 work with this. I highly recommend it if you’re as frustrated with WMP12 as I am.
If you’re looking to find a way to stream Hulu, Comedy Central, YouTube, etc., etc., get PlayOn by Media Mall. Another great program that I highly recommend. It’s $20, but worth it. Especially when you go to their plugin page and add other great sites like Vimeo, 66stage, Sci Fi and many others.
