Well we are into about the third week in our beta cycle.
Both the iphone and ipad apps work fairly well with ps3mediaserver if the content follows the mpeg-ps spec closely.
If someone would like to setup a renderer for p3media server that transcodes to mpeg-level-2 , mpeg-ps than it would even be better.
Right now our resources are spread kind of thin so we don't have the time.
The current version of the app works fairly well with the following servers, best performer order.
