Recuring playback cut (re-buffering) and admin right problem with the 7.7.2 - r33893

[resys]

Since the upgrade i was experiencing playing cut (re-buffering).
This during radio playback and library playback.
At the beginning a reboot of the PC was enough.
Time after time the cut was happening more and more often.
Since 2 days, the reboot of the PC wasn't solving the Issue.

I also had the admin right problem.

I installed the nightly 7.8.0. everything was working right expect the fact than the full library scanning was looping.

So I installed back the 7.7.1 and everything is now OK (one hour for now)

Maybe useful to someone else or to dev people

C U

Edit : now 3 hours without problems
