2009年1月9日 19:07I've been using Vista Media Center for a couple years along with a Directshow filter "hack" to play media encoded with X264. I was overjoyed to hear that native h.264 support would be in the new Media Center, since functionality got wonky in Vista Media Center after installing all the ____ to enable H.264 playback. Unfortunately, I'm really disappointed in the quality of the decoding job being done in Windows 7 Media Center. It's detectably choppy to the point where it's a bit uncomfortable to watch, but not terribly, and never stutters. The picture is a bit blockier, as well, compared to FFDShow in Vista Media Center. Has anyone else encountered this? I hope it will be improved before RTM.
2009年1月11日 22:06the same is true for me - Some videos will play fine while other's won't. I have some videos in 720p in avi which have problems because audio and video are not snychron.
2009年1月12日 17:52Have you tried DivX 7? It has native H.264 support.
2009年1月13日 22:41Well, I was able to get an .MKV file to play (see http://social.technet.microsoft.com/Forums/en-US/w7itpromedia/thread/bb446977-867b-41f1-9d9b-0d96a5bacf20) , but... there's definitely no hardware acceleration, CPU usage is high and the video lags way behind the audio.
My video card (ATI Radeon HD2400 Pro) has built-in H.264 acceleration, and I was able to get it to work under XP. On 7, I'm using the latest Vista driver 8-12_vista32_dd_ccc_wdm_enu_72275.
