[QUOTE="markius, post: 479580, member: 28097"] [b]XP double decoding[/b] Hi all So I've just rebuilt my HTPC with Windows XP (SP3) after battling with Vista for a year or so. Don't know why I didn't do it sooner. XP is so much nicer. Anyway, the reason I am here... I have a problem with HD playback. I installed XP, all updates, dvbfix etc Then installed MediaPortal Then installed SteamedMP skin Then finally installed SAF347 (and matroska splitter) using PowerDVD codec. I also downgraded to Catalyst 8.5 as per the warning during the SAF install. SD rendering is as perfect as SD can be. HD doesn't seem to work at all though - no picture, no sound. Using GraphStudio I can see that "double decoding" is happening for HD streams: MP File Reader -> MPC Video Decoder -> CyberLink Video/SP Decoder (PDVD9) -> VMR 9 So reading few a few posts here I unregistered MPCVideoDec.ax After doing that, I get HD audio but still no picture. Another trip into GraphStudio revealed that no video decoding was happening at all. MediaPortal config now doesn't show any available H.264 decoders. So... how do I fix this? FYI SD decoding uses MP File Reader -> Cyberlink Video/SP -> VMR9 Cheers Mark [/QUOTE]
