I deal with that problem several days and was searched up tens forums and asked about help, but still not success. I'm just love MediaPortal logic and nice interface and thats why I dont want to give up. There are 2 type of issues.
1) MP doesnt play some avi files (in example videos XVID with AC3 codecs, lets name that File A). In same time MP plays other avi file (Lets name it File B) with same codec combination. Also, seems that all other mediaplayers (BSPlayer, MPC_HC, XMBC) playing File 1 ok. I discovered that same issue are with some mp3 files. Its just doest play this (says that unable to play and announces codec type).
2) Second and more serious problem is with H.264 files. I have Zotac ION (ITX) with Atom 330 processor and Nvidia 9400 graphic card. I tried tons of settings, loaded MPC-HC ax standalone codec, loaded Cyberlinc codec, because I understand that MP doesnt support Nvidia Purevideo technology. Or vice versa. Anyway MPC-HC plays same 1080p video smoothly but in MP it is so jerky that is unwatchable.
