It would be great to get some feedback on the LE10 testbuild as well, initial testing here looked good, but we'd like to have some more positive confirmation that things work as expected before adding the backport patches to official LE10 releases.
Installed on my spare machine, so far so good. Have flicked through a few channels with 1080i content and it looks as good as my main Intel HTPC. TV isn't 4K so haven't had a chance to try that or HDR etc yet.
