Not necessarily. You don't have to connect the PC directly to the TV using a VGA cable.
With an HR20 and wireless bridge, you can stream the MLB feed using Windows Media (I think).
Besides that, many PC's, especially laptops, have a video output to composite video.
Many people want to feed the output of MLB.com or any signal from your computer to the TV, but the TV is at the other end of the house. It can be done in many different ways. Here are a few:
1. Sometimes if you have an audio and video output from your computer, you can use a wireless transmitter and a receiver to send it from one room to another. This may work, but it has one big downfall. You could pick up interference from your or a neighbors wireless networks, wireless phones or microwave ovens. They come in two different frequencies 2.4 gHz and 5.8 gHz. Usually the 5.8 will have less interference. You just plug the video and audio outputs from your computer, into the transmitter. Then on the TV side, you plug the audio and video outputs from the receiver, into your TV. Here is one example of a receiver/transmitter setup. There are many others out there on the market.

2. If your house is hard wired with Cat 5 or Cat 6 network cable, you can use those lines to send the audio and video, from your computer to the TV, with the use of baluns. Baluns convert the audio and video signal from the computer, into a signal sent through the twisted pairs of a network cable. If your house is not network wired you can run a network cable between the computer and the TV and accomplish this also. You can even send HD signals over network cableing, using baluns, but it requires two separate network lines, one for audio and one for video. Here is how you would wire using baluns. You need two audio video baluns, one for the computer side and one for the TV side. You plug the video and audio output from the computer, into the first balun. Then go to the TV and select an unused audio video input, on your TV and plug the other balun into it.
Then, if you have house network wiring plug both baluns into the network connection, near your computer and near yout TV. Remember if you have network wiring, remove those two lines, the one from the balun at your computer and the one connected to the balun at your TV, from any routers and jumper them together at your patch panel, to create a continous uninterupted line between the baluns. Then what ever you have on your computer will be outputted through its a/v outputs into the baluns, into the network wiring and to the other balun. Then from the other balun to the A/V input of the TV.
If you don't have house wiring, just connect the two baluns together using a Cat 5 or Cat 6 cable.
Here is an example of the baluns you can use:
