Everything *except* live & recorded TV (using the MP TV plugin in RTSP mode) will use the equivalent of the 'UNC paths' method i.e. Windows SMBx protocol to read remote files. SMB is a 'reliable' protocol with handshaking and re-transmission etc., but RTSP isn't - the data is just pushed out by the server, if the packets get lost in the network they are gone forever - there is no re-transmission.

If these network problems have got worse recently, have you checked/swapped the cables etc. ? The problem with networking is that because the common protocols (HTTP, FTP, SMB etc) are designed to handle packet loss/corruption, the network performance can degrade without it affecting most traffic - except for things like RTSP which are sensitive to it.

The actual data stream port number is allocated dynamically, so it will change for each new stream. Port 554 is (I think) the port used for stream setup and control.
