Firstly, rather than add "me too" to someone elses post, it's much better to start your own. I've done it for you now - rant over!
Righto then - what's the issue with your 360, what makes you think it's a fault?
In terms of your second question - VM staff respond to posts on here, but it's not a real-time service. It's primarily a community forum where the first responders are other users, and anyone wanting to help you needs to know details of your issue.

streamed programmes are unaffected, the play perfectly
