Wdtv slingplayer problems

I am not having the noise issues but video freezing.  Just bought a new WDTV Live+ and a used slingbox solo, only wanting it for this use.  SLingplayer works fine for a few sedonds to maybe a minute, then video freezes while audio continues.  All other WDTV controls dodn;t work.  Only way ut is to access slingbox from another device and kick the WDTV off.  This only works for a while, but if left alone the whole system hangs and can only be reset by unplugging it.  Has anyone else had and/or solved this?  BTW Slingbox iss connected via ethernet, port forwarding enabled properly (I think) and WDTV is voer wifi (other services all working great via wifi, so good connection).
