I bought my WS6 Mater 2 months ago and software version it came with .71 . I was waiting to upgrade when version 4.1 came out . From what I read on the WS6 Master it will not play in Stereo so the V 4.1 will not benefit from this software . I need information from people that use the puck not from remote owners . If the this is true what is the best version to run . Let's say that I do update too 4.1 does this do all the other update from .71 to 4.1 ? Another place I can get some info ? Thanks for your help.
