Hi. I now have to install my 11HT. Tomorrow, I'm gonna buy a screen(hopefully Da-Lite Cinema Vision), a ceiling mount kit, and 15M long component video cable. How do you guys who owns a projector install these kind of things? Do you drill walls and install them on your own? or do you pay "professional" guys to do the installation for you? I have no idea, since I've never done drilling walls or installing a projector, anything like that. Can somebody give me an idea how you installed it and what you found difficult? Any comments, advice would be greatly appreciated. Thanks.
