streaming to multiple HD1K units

Hello all -

I have been using the HD1K without problems thus far. I have a LinkStation 
connected directly to the unit and plays HD transport streams fine (I did 
notice the when it first plays it has difficulties). I am wondering if anyone 
has tried streaming multiple videos to different units at the same time? i.e... 
one LinkStation to two or three units playing the same video stream - or 
different videos.

Thanks in advance to all that reply,
bS
