I often watch video via my Roku.  Netflix, Hulu, Amazon.
Often, I can't get the audio to lock in and I get a bunch of noise.  Sometimes this can be remedied by cycling through inputs on the SP-3.  If I do this sometimes the video gets messed up and is all green.  Other times I need to shut the SP-3 off and then back on.
Do others have issues with Rokus?  This seems like a handshaking issue but I can't say I understand it beyond that.
