[QUOTE="Taipan, post: 214135, member: 11681"] I don't have any personal experience with analogue TV cards, so my comments are just suggestions/guesses ... ;) You are referring to the analog side here - correct? The DVB-T side is working fine? This might have something to do with VMR9 versus Video Overlay modes? MediaPortal uses VMR9 and I am guessing that WINDVR3 uses Overlay. Have you used GraphEdit to see what encoder/decoder combination is actually being used by MediaPortal and compared that with WINDVR3? If you record some analog TV, but not view it at the same time so that only the encoder is in use, what CPU% do you get? If you then view the recorded analog TV, what CPU% do you get? Do you have DxVA enabled in your video decoder? (CyberLink?) [/QUOTE]
