I just bought a brand new laptop with windows 8 on it and I've been trying to find the right codec to play all my movie files, none of them seem to be doing anything. The videos will play, but the visual quality is super poor, spotty, blocking, with lines and stripes seen especially when graphics are dark. All the movie files I tried work perfectly fine on my old computers (XP and Vista) with the codecs on them, but on this new one, I tried K-Lite, Shark007, DivX+, Xvid, pretty much every pack I could find online, none are solving the issues whatsoever! Can anybody enlighten me as to what to do? Is there something entirely different I need to do to configure my WMP in order to play these files in high quality? Please help!
