I would like opinions on which viewing would be better for my situation. I am in the process of building a HT room and my approximate room dimensions are 14'W x 21'L x 7.5'H. These dimensions are somewhat flexible. I don't know what my viewing distance will be at this time. I plan to watch mostly DVD's but would like to watch HDTV and well as SDTV up converted via a DBS tuner. One more question, what is screen door affect?
