latimers: I've been having the restart issue for a while now
The next theory was that Freeview has changed something in the signal and that is causing the restarts. Dish TV provided me with a beta version of the 3.19 firmware and asked me to see if that solved the issue. It didn't.
Does your restart issue occur right after waking up the Magic TV from standby, i.e. displays video briefly then restart within 1 minute?
3.19b1 or 3.19b2?
