1) I have a Sony Vaio with A/V inputs in the front and back. However, I cannot find any programs on the PC to utilize them and Sony people keep telling me to use an app that doesn't work. I'm trying to use my XM SkyFi2 home system that has Audio L/R inputs. Any ideas?

2) Is there a way to individually mute a program (such as media center) in XP MCE 2004?

TIA!
