Hello Peeps Sorry to sound thick, but what is this HTPC business you are all mentioning? I am considering a Panny PT AE100 and would obviously like to get the most out of it. I don't have a PC and I am not likely to get one for quite some time, so is there some sort of image improvement device I can use which will (I presume) connect between my DVD player and forthcoming PJ. If you decide to use words such as "Descaler" and "Line doublers" etc. in your replies, could you briefly explain what these items are? I used to be fairly au fait with hi-fi and A/V, but things are starting to fly way over my head, especially in the projectors department.
