Once your computer is connected to your 21” TV you can use Media Center to keep track of your media files and handle your DVR recording needs. If you want to record TV without using Media Center, similar products on the market can do the job. For example, SnapStream's Beyond TV comes bundled with many TV tuner cards, so if you're building a home theater or upgrading a machine you already own, you might end up with a copy by default. And you can take a further step and add the Beyond Media program for organizing photo, music, and other media files, and it does pretty much everything Media Center does. Beyond TV doesn't support every TV tuner card on the market, so check the hardware specs for your 21” LCD TV before you install it.
