I am a huge fan of HDTV's and have been drueling over them at Best Buy for a long time. My current favorite is the Samsung DLP. I would like some definitive explanations of the different resolutions and formats. I'm not even sure what exactly to ask, but I will start with a specific question, and please fell free to elaborate and go off on as many tangents as you like! The Samsung DLP is listed as 1280x720 resolution, and it also says that everything is converted to 720p (what is the p?) format. But, the Best Buy guy told me that the tv is also capable of 1280i. I don't really understand the difference, and when I see something like #x# I assume that it is dimensions, i.e. the tv has 1280 pixels width-wise and 720 pixels height-wise. All I know for certain is that the bigger the number the better the resolution, and that regular tv is 480i (what is the i?), and that the most common hdtv format is 1080i.
