So I recently got a radeon 4890 graphics card and pretty much every one of my emulators run wonderfully now.

My question is, would there be a way to send the picture/audio from my PC to my CRT and play upscaled ps1 games that way? I know there are some VGA adapters out there but haven't found one that ends in s-video with audio jacks. PS1 games are extremely low resolution & I would love to play some one my Ps1 games with scanlines on an old tv if possible.
