I got an old 1.6G pc 512MB 80G DVD-RW. 1. Buy a graphics card with DVI out and a Sound card with DIGITAL 5.1 out. 2. Install a software which is free or cheap and does great upscaling to output to HDTV. 3. Now it plays DVD movie from the DVD-RW drive and the software upscale the signal to fit HD resolution and output to DVI to HDTV. 4. Digital 5.1 signal from DVD is sent to AV receiver. Is this possible? What do I need to buy? Any recommendations please?
