[QUOTE="sns2015, post: 339492, member: 75686"] As far as I know I'm not using any extra filters to resize to 1080p, which makes this an extremely strange issue indeed. I also tried yourmumquake's suggestion and it didn't fix the issue. Part of the problem is that my 3450 isn't quite enough to offload 1080p material fully (and even if it could, it would still have to be level 4.1, which most stuff isn't) and what remains is still too much for my CPU to handle, so going with just a DXVA solution doesn't really work. I did find out, however, that this issue is only limited to h.264 material in MediaPortal. It seems that I can play back DivX/XVID and MPEG-2 videos fine regardless of resolution, it seems that it's just x264 that's broken. I get the feeling that it may be that the internal scaler used by VMR9 is using an unnecessary amount of CPU than it would otherwise normally do outside of MediaPortal.
