Hi Folks, Had a quick look around and didn't find anything that quite looked like the same problem I have, but forgive me if it's been raised before. This may very well be a Sony issue, rather than Mac, but wondered if some smart person here might be able to help. Bought a Mac Mini Server a couple of weeks ago and love it. Got a Magic Trackpad and Bluetooth keyboard too, so all is great and wires are virtually non existent. Plugging into my Sony Bravia direct using hdmi (port 3 on telly) is a pleasure - great pic and no problems. Until I switch on my Sony Bluray home theatre, which goes into hdmi port 1 of the telly, at which point the trackpad response becomes very jumpy and inaccurate and the connection to both the wireless keyboard and trackpad gets lost, reconnected, lost, etc. Using a USB mouse and keyboard gets rid of the jerkiness ( works fine in other words). Moreover, if I connect the Macmini directly to the home theatre's hdmi port, using it as the gateway to the TV, and which works fine for my windows laptop, the picture on the telly goes blank for a second or two every five to ten seconds or so, like the system is synching over and over. Any thoughts? All is connected correctly, so I'm wondering if there is some Mac secret all you long time users know that I don't? Any help much appreciated.
