Something else weird was happening. I was checking to see if changes took place if I manually sync'd and they did. However when I switched back and forth to playing here (laptop) to play there sync failed advising saying to check that auth was set. It was. Changed back and forth again and still got the error. Closed and opened and it was fine again, made said changes = error again!
Anyway I went back on htpc wiped out the media network settings and started again now everything seems fine and my changes are syncing + no errors when I change play to and manually sync. So somehting is weird here...
