I have 2 of these machines and have not had any problems before. I found them both on Friday night with no picture or sound (Black screen) but I did have some very limited control and could still view recordings. However from this morning (Saturday 20th) they are both stuck in Update and absolutely no button works (on the remote and the unit itself) - obviously an update gone wrong - especially with seeing how many others are affected - and we have to wait until Monday?????? (and then if we are lucky).

This is going to be interesting.
