Simple.
Video: DVI to monitor ( or possibly RGB).
Audio: SAT TV + DVD to monitor, then out to A.AUX socket at the bottom of the BS 3200. ( I've tried TV analogue to the PC, but the resolution is abominable. )
Additional thoughts:
I purchased 10 BOSSCOM wall sets from our sponsor Lee, which include a very smart looking wall plate with an M-L and PAL connector ( or NTSC connector replacement ). But today, with 1080 HD you need component. For that I purchased a small roll of RG-6, pulled my own cable, and made my own connectors.
Expensive Component cables, even if Monster gold-plated, gold plastic encapsulated, or Swarovski " diamond " encrusted, is still simple RG-6.
HDMI, being digital audio and video of course solves this problem with one small cable connection, if under 4 + metres. Any further length requires a signal repeater, but some manufacturers are now building a signal repeater nub into the cable.
This works with our main, but somewhat older B&O system downstairs, and 2 BV 8 upstairs, all M-L linked. We have found that this also works in Europe as well as North America, at least for today. Tommorrow ? We see better potential in BS 5.
