I don't really stream any videos over the network... but if I do then the 360 is set up with WMP for that and it actually works great.
The only thing I use TVersity for is to stream flac files to my denon. All of my mp3's and videos are streamed with WMP... that way I can access all of my flac files by going to the TVersity server and not have to dig through a bunch of crappy mp3's (most of my mp3's are at a horrible bitrate).
My TVersity server does have a tendency to say "not authorized" a lot and I have to run back to the computer and hit the "reset server" icon that I placed onto my desktop... kinda a pain.
