HiHi again
Port 554 is used for RTSP streaming control. The video and audio data is sent over high range "anonymous" ports. Have you tried disabling firewalls to see if it makes a difference? We have had reports of problems with firewalls especially on 64 bit versions of W7 in the last year. MP and TV Server must have access to public *and* private ports. Sometimes it also helps to re-add exceptions. Having said that I'm completely guessing about what could be going on here. It would help if you could post logs [for the client *and* server] showing what happens when you have the problem.
