Well, I have TVersity up and running. My complaints so far is that when I load up my library, it takes quite a long time for the full list to come up on my PS3 (I have about 10,000 and less than 100 videos), and also when I play videos, the video stutters a lot - probably about every other 5-10 seconds. Could it be that the WIFI isn't cutting it and maybe I should go wired? As a comparison, I have my 360 wired to the router with TVersity up on there as well. I played Baby Einstein video for my baby and not one stutter so far.
