HI, I have been trying to stream .MKV's with various methods and ps3mediasevrer is the only one I had any luck with. I un-installed all my codec pack, then installed, CCCP, AC3 filter, AviSynth and finally Haali media splitter. I set it up excatly like it was said in the FAQ/HELP tab with a few settings of my own like video scaler. When I had finished setting up, I had to go into the media bladdes on the 360 to get the server to connect with it and from then I had no problem streaming 720p .MKV/.X264 etc to my 360 over my wireless connection, using my Sony Vaio VGN-FW21L Laptop (Intel core 2 duo @2.00 Ghz, 3GB ram)
After a bit more rippping of 1080p Blu Ray movies, I found I didn't have enough network Bandwidth (i think) to stream without choppy results
. I will be trying to stream them wired as soon as I find my old wire. My network only goes to 54 Mbps where as wired isn't limited as such.
Try these and I think you will be surprised how easy it was.
Let me know also if you managed to stream 1080P wirelessly or wired.
