I built an HTCP. Everything is working great, except...
If I switch my TV to another input (say to the PS3) and then back to the HTCP... WMC is waiting there for me with an error prompt which forces me to close WMC or restart it.
It wouldn't be so bad if that didn't mean that my paused (live) tv is now gone.
I don't have a video card, just running video off the i3 2100 chip. The PC is connected to the TV through HDMI as the only monitor.
