Yesterday I tried to stream 1080p via 2,4GHz 802.11n. My test films where Gladiator Extended edition and Avatar. Both movies played fine, only if the data rate where to high it beguns stuttering.
I first tried with a NFS-share on a QNAP 109Pro II connected on a Fritzbox 7270, because I though this is the best option. After it I started the Twonky Media server on the QNAP and tried it via uPnP. It also beguns stuttering at the same scene but not that much and also some seconds later. Maybe this comes from buffering of the Twonky, I don't this server.
Later I made an update from 2.0.1 to 3.0.2, because I want to check if maybe the performance is a little bit better with the new version. But it looks that it was a little bit slower, because the stuttering via uPnP beguns earlier than with the older version.
Now I want to ask, which method is best to use for streaming? I know, that 1080p isn't working smoothly at the moment. I want to try it again via 5GHz the next days. So this is maybe only some theoretical question.
Does anyone has experiences with 5Ghz? If I'm right there is only the Apple Airport Express and the Buffalo WLI-TX4-AG300N as a possible solution for 5GHz and 802.11n. Does someone use one of these two methods?
