Ever since installing MePo 1.2.x I'm grtting severe stuttering on live TV. I never used to get this before but since 1.2 was a fresh install maybe I have non-optimised config? I have tried various drivers (including latest) & decoders (SAF 6) but no success. I run MePo with screen settings of 1080p. If I reduce my resolution to 1024x768 then the stutter stops and frame rate increases! Any idea what to do?:confused: Other applications (Prog dvb & media centre) don't suffer from this issue.
I have attached logfiles as described with Live Tv running at 1920x1080
