I've spoken to Applecare, they referred me to my local geniusbar. So I duly trekked down there and they took my MBP in for a couple of weeks. It came back with a new MLB (main logic board) and of I trotted, happy that my problem was duly fixed.
And so it seemed. I use my mbp for work and it played happily for the first day.
Day 2 however and the symptoms returned. As you can see from the log entry above, i've been impacted today - twice already, so i'll be going back to the geniusbar. At the moment as a full on work machine, imo, my mbp is not fit for purpose.
First mac, was greatly impressed at first. And still love it when it works, but this is bugging me greatly!
