Hmm. At the moment i'm having problems with AppleTV with 8.04 ubuntu. I have compiled latest boblight from source.
I'm using latest LEDstream.pde with Arduino Duemilanove.

I'm using pin 11 and 13 and gnd and 5V 3A from external power supply.
All the other settings are like in this tutorial that i have wrote.
Does someone has any idea what could be wrong?
