First off, when I look at pictures, play games, etc the graphics are clean and spot on. However, when I watch a Blu-ray in PowerDVD 7.3, it all appears grainy and dirty, if you know what I mean. However, I'm not even bothered about bluray yet. When watching a DVD is MediaPortal, the quality is unbearable. For a start, where it tries to put a film as 16:9, you get this stupid greying bands at the left and right of the screen. Also, the picture quality is absolutely rubbish! I have even followed several of the online upscaling tutorials. Some enhanced DVDs will not even play! They crash MediaPortal. I find it hard to swallow that a £1200 HTPC will not even display a DVD remotely good, let alone better than a £200 Tesco's jobbie!
