    I admit to being a little confused with the rate of new formats coming out and so am after some basic advice.

    Ive a setup of a Panny 50" 1366 x 768 plasma, connected to my PC by VGA.

    I obtained a demo disk of HDTV material, its source resolution is 1920 x 1080.

    Using the ATI Control Panel (Ive a radeon x800 Pro with two options to force 720p at 60Hz and 1080i at 30Hz), I forced the 1080i resolution and proceeded to watch the demo using the newest version of Power DVD, which indeed did look nice and crisp.

    The image looked very nice at my desktop setting of 1280 x 720 also.

    Am I watching what can be described as actual HDTV as its intended, or am I missing or of misconfigured something?

    the 1080i picture is being scaled down for your tv's 1366 x 768 res but this is higher than 720p so yes you were watching it in HD

    Yes - though it is worth knowing that some displays (quite a few) treat 1080i as 540p when scaling to 720p or 768p - so don't exploit the full vertical resolution of 1080i. (The better scalers de-interlace 1080i to 1080p not 540p on the way to 720/768p)
