Hi Guys

Has anyone come across this problem, I have a customer who has a Beosystem3 with software updated about 3 months ago, I have an isue with both macmini connected via mini display port to hdmi, and sky hd connected via hdmi, what is happening is after they switch it of at night. The next  morning they switch it on from stand by, it comes up saying source is proteced with a blank screen, the only way to resolve this is switch it all of at the mains then back on again then it is ok.  Im using good quality HDMI leads. There is no scart in the sky hd box, wondered if that would explain it, however the macmini is doing the exact same thing, if anybody has any thoughts it would be appreciated.
