Hello, here's a strange one for you. I have a Pi plugged in to my TV using a HDMI cable. I'm running Raspbmc RC5 on the Pi, and i leave it running 24/7.
However, sometimes when I'm watching TV (not on the Pi) the picture will start to artifact then break up completely. I can resolve this by unplugging the HDMI cable from the Pi.
I haven't established a pattern for this behaviour yet. I managed to watch Homeland on TV last night without issue, my wife managed to watch other programmes too. However, around 8.00 this morning, the interference appeared again.
My first suspicion is that the HDMI cable I'm using isn't adequately shielded, I haven’t tested with a different one yet. I’m wondering whether anyone has any other ideas?
