Here's an approach I use that works reasonable well. Most people have laptop computers so I put mine to some work! I got an Express Card (HP Digital Tuner) and plugged it into the card slot on the side of the PC. Then ran Microsoft Media Center software, comes standard with Windows Vista. The laptop has a composite video output which feeds an agile modulator. The modulator output is easily tuned to the desired TV channel. I found this approach to be fairly inexpensive, requiring no modifications to a TV. Small enough to be placed inside a TV if needed - at least where cabinet space permits. The only thing I splurged on was the Express Card ... $35.00
