Ok,
I bought the new netgear 500mbps homeplugs so i could stream my hd video from my nas server a ds411j. Upstairs I am getting good transfer rates of abouyt 14 MB/s- 16MB/s. Netgears tool shows a Tx of 420mbps. So getting about a 1/3 of throughput.
Now when I plug in downstairs the netgear tool shows a connection of Tx 221 mbps so as expected I lost a bit but still a good connection. I streamed some a 12gb mkv to my laptop from my nas using copy paste in the laptop and I was getting a steady 9.9MB/s so all good I think. Plug the ethernet into the wdtv and then try and watch a mkv. No good it stutters after a few minutes. I tried a few and some seem ok. I then connected an external hd to wdtv and streamed a file to it from my laptop upsatirs. Connection a steady 5.9 MB/s which I thought was good enough for HD?
Any thoughts on why some would stutter here is the info of the file I have been using to test:-
