It's an Att home network and I'm not sure how to improve the speed. I could use a wired connection but that would defeat the purpose of wanting to stream to multiple tv's. I am using my laptop on another tv from my HTPC that is in the basement in the theater room. I had started another thread asking about the best streaming devices but what I discovered is is that the files are too big for my network. The funny thing is though is that my Iphone can stream all the files wiht no stutter using Video Stream app. I believe the app converts realtime.
