Come on now, you'd have to check a few things:

(i)   format of the source stream. Likely to be ok, because it probably
       plays fine from hard drive.

(ii)  efficiency of cabling, switches, hubs etc.. if the ping times are
       low, this can be ruled out.

(iii) efficiency of the TCP/IP stack on the receiver. This is a hornets
       nest of possible problems. But it would be possible to measure
       latency between the interrupt for the network port and the time
       that the packet arrives for processing by the application.

(iv)  efficiency of the program. Is there latency introduced within the
       player.

To find out the source of this problem, experimentation is exactly what
would be needed, ruling things out as you go ..
