Newbie Help - MLB.TV

I'm not sure this is the correct forum to post this question in, but it seemed the closest to my needs.

I'm wanting to watch MLB.TV streamed over the internet on my TV in the living room. My PC and internet connection is in a room about 10-20 feet from the TV, though.

I've considered upgrading my 2nd PC to a media center and using it's wireless connection to my router to get the internet connection for MLB.TV, but I would probably need to invest in a new video card with TV out. Plus, I'm unsure how to get the video to full screen instead of a window so it will output correctly to my TV. Advice, please?

Another option I am considering is a D-Link wireless media server that will work with my main PC and allow me to watch whatever content I have on it - video files, audio, etc. Does anyone have any experience with something like this?

Thanks in advance for your help.

Thanks! I was thinking the same thing about the D-Link media server. I'll probably go with upgrading my extra PC and hooking it up to the TV.

I'm trying to cover my bases since it looks like MLB Extra Innings will be going DirecTV exclusive.
