I really like this software. It's got the best interface of all the "media server" software out there. I use media server software primarily to stream movies to my PS3, which means this software has one glaring drawback for me... no 5.1 audio.
I know that by "default" the PS3 only accepts 5.1 audio from disc media, so the fact that this software converts the stream to 2 channel stereo makes sense. BUT, and this is a big BUT, "PS3 Media Server" software has found away around this and streams MKVs with full 5.1/7.1 audio to my PS3 beautifully. Knowing this is now possible, all other media servers (who claim compatibility with the PS3) need to immediately jump on the bandwagon here. This is obviously a well crafted piece of software, but I simply can't use it because of this one failure. I'm not that keen on running 2 media servers at the same time, and since I primarily use it for streaming movies, PS3 Media Server currently serves my needs better.
I will be keeping a close eye on this software hoping they get up to speed on streaming digital audio to the PS3, because as soon as they do, this will become my preferred software.
