[QUOTE="kiwijunglist, post: 671140, member: 76888"] I don't know what trailing images means... Generally the problems can relate to 1. Video tearing 2. Dropped frames (press SHIFT+1 while watching a video) 3. Video + audio out of sync, often same cause as #2. 4. Sharpness / artifacts, usually caused by lack of 1:1 mapping and using video processing in CCC eg, sharpness etc.. 5. Interlacing method 6. Video glitching (blocky coloured artifacts), usually caused by codec, driver or reception/interference issue Vista is just bad in general. Which is why i recommend XP SP3 or Win7 32bit. I recommend 32bit for HTPC, as there isn't really any advantage in going 64bit as MP is a 32bit application. 32bit limits the amount of RAM, but MP on an HTPC doesn't require that much anyway, so it's really a moot point. Anyways OS discussion is probably outside the scope of this thread. I think an important thing to check with regard to sharpness is that you have 1:1 pixel mapping. Google "tigerdave 1080p test pattern" and ensure you have 1:1 pixel mapping. [url]http://pixelmapping.wikispaces.com/Pixel+mapping+explained[/url] or view this image on your home pc in your browser window [url]http://upload.wikimedia.org/wikipedia/commons/1/15/Effects_of_overscan_on_fixed-pixel_displays.png[/url] zoom into the picture at 100% zoom, then zoom out and notice how the left hand 1:1 pixel map pic changes when you zoom in + out. view the same image on your HTPC at 100% zoom [/QUOTE]
