Am new to the HTPC scene and would like to learn more about the software aspects of the HTPC. 1)I would like to know what types of software you guys use on the HTPC (other than the OS, of course!), especially to process the audio and display. 2)I have read and heard about doubling the scanlines of the display with the HTPC. What types of softwares are involved? 3) How is PowerStrip useful in the HTPC? Any relevent input will be very much appreciated.
