[QUOTE="splatterpop, post: 1051847, member: 62445"] Ok I want to share my latest learnings here. 1. SVP Project [url]http://www.svp-team.com/[/url] provides a refactored version of mvtools, along with a control program. While some problems, like artefacts, persist, others are solved, such as distorted image during seek, adapting to HD material and the necessity of avs coding. 2. HDMI limitations As far as I was able to find out, HDMI specifications do not allow refresh rates beyond 50Hz at 1080p resolution. There are reports about attempts at tweaking the EDID or overclocking the graphics adapter, but it seems there are as many reports of failures. My conclusion is that for the classic living room combination of HTPC, HDMI cable and HD monitor, 50Hz is the limit. 3. Higher refresh rates Refresh rates such as 100Hz and beyond are possible only if frame interpolation is shifted away from the HTPC into the monitor hardware. It would be interesting to learn which monitors have such capabilities accessible through HDMI (not just the internal tuner, like mine does) Cheers, splatterpop [/QUOTE]
