I just got my htpc setup with a Key Digital transcoder (vga to component adapter). I did all the reading on how to tweak with powerstrip on pages like http://www.keohi.com/keohihdtv/exper...uperguide.html and http://www.ramelectronics.net/html/powerstrip.html. Then I set mine to 960x540p and got it to work and it resulted in a great picture with a fair amount of overscan. I used the tricks that I had read about powerstrip to get rid of the overscan and then I began testing higher resolutions. I got 1920x540p to work! Using Zoom Player, I can mess with custom aspect ratios until I get all of the picture on my 47" panasonic with no trouble (by the way, this is a very forgiving set that can handle a wider range of scan rates than the powerstrip guides suggested typical hdtv's would!) I then proceeded to check which was better, my progressive scan dvd player or my htpc. I was astounded by the results! The HTPC is AMAZING. Once it was calibrated (avia wasn't nearly as helpful with the htpc as it was the dvd player!) and maxed out for resolution, the difference became obvious and I won't watch another dvd on my stand alone progressive dvd player again. Also, one last note, I did get 1920x1080i to work but it put out such a horrible picture quality for both video and, mainly, desktop/text that I couldn't realistically deal with it. Now I just wish I had an HDTV that could truely do 720p, I can only imagine what that would look like!.
