Well I finally got my HD1000U and I love it. Today I got it ceiling mounted and noticed a problem. Recently, I had a ground loop issue and I bought all new cabling for everything and a new surge protector and it went away. Well, when I got the projector ceiling mounted, the loop problem came back and worse! The only thing that is different is that the projector is plugged into a different outlet than it was yesterday (the last time I used the projector and there was no ground loop issue. Could the outlet I now have the projector plugged into be the source of my problem?
