Various companies already produce software to make your PC or laptop into a media centre.
Microsoft have a product called Windows Media Center Edition that was part of Windows XP (it is also built into some versions of Vista).
This runs on an "ordinairy" PC that has a TV tuner built in, and has a remote control, picture here:

Using a PC attached to your TV running this version of Windows you can watch TV programs via the PC, record programs on the PC, look at pictures or videos stored on the PC, listen to music on the PC and so on.
More and more companies are producing "media" PCs that run like a PC, but look like a DVD player, here is an article about one.
