So do you have issues when watching pre-recorded content and the HDHR is 
not streaming at the same time?  If the issues are with two or more 
concurrent streams but not with one, then I'd highly suspect network 
bandwidth is the cause.  There are tools to monitor bandwidth but with 
standard home network switches, you can not span a port and thus would 
not see the entire picture, rendering those tools somewhat useless.  But 
if you had an old "hub" you could put in there...  :)

Cheers,
