One of the things I've noticed on the new build is the option to choose a scaling method. This option is available both in the Settings/Video and by bringing up the OSD/Video Options during playback.
In the Main settings menu there is one extra option "Lanczos" that is not available during playback in the OSD options.
Nevertheless, regardless of which option I choose (or where I choose it from), I don't see any difference in the image quality.
I tried the same experiment on the Mac version of XBMC and the image quality changes are instantly visible, especially from "Nearest Neighbor" to "Bicubic".
Are these functions impelmented yet
?
Something else on the new build is that VOB Subs actually "show on screen"... sort of. On a couple of movies I have with VOB subs, I now get the occasional random sub appearing. Not every sub is shown, just here and there, but before there was nothing. This seems to be a problem shared with the Mac version.
Last but not least, GMA950 does not work. You only get a black backgournd or a white background during movie playback. You get audio, but no video. This problems is already being discussed in another thread.
