------------- Artificially split it using a driven "ground" in the middle.

Hi
I have used a TLE2426 for such a purpose. It gives you this ground in the middle. I had some problems though. The virtual ground wasn't perfect and I had some (barely visible) crosstalk between two different video signals, and I think it was due to unstable virtual ground. I guess that you wouldn't encounter the same problems as audio is slower and you will have the signal signal feeding both amps. It's worth a try. It's a cheap device.
