Choppy Sound

I have a WD TV Live Plus when trying to play Netflex movies the audio is choppy comes and goes. Tried updating to firmware version 1.04.22_b but have the same problem… Any suggestions would be helpful.

Here is my network PK 5000 to Cisco Switch from the Cisco switch I have WHS and several workstations…also have a cat 6 cable to a netgear porsafe gs108 switch from here I have one computer, WD TV Live Plus, and Blue Ray player.

I’m no techo, but have noticed that my PVR (Tevio) sometimes chops sound… usually after a fast forward past the adds… when this happens I  now do a very short rewind… which then restores sound… Maybe the buffs can work out the techo stuff from that and come up with a fix.
