I've been using PS3 Media Server to stream video to my XBox 360 for a while now, because I don't like the whole Windows Media Center Extender thing (I also think I tried it at one point and it won't stream this type of media). Some of it is HD, some SD.
Just recently, HD video (example: 720p, mkv, ripped from BluRay) has started to lag behind its audio. For longer videos - like an hour long TV show, or a 2 hour movie - by the end, it's extremely noticeable and annoying.
I know it's not the video file itself that's out of sync because if I watch in on the computer it doesn't lag at all. I'm pretty sure I'm using the latest version of PS3MS, too.
Does anyone have any suggestions for ways to fix this or alternative solutions?
