Gordon Johnson, do you get any issue by playing DVD or Blu-ray with a different media player software? Please check if there are any yellow bangs in Device Manager.
Johnny_Bear, I mentioned that I will communicate your inquiry but I do not want to create false expectations. We have solved several different issues since the upgrade as you may read through these pages. I do agree there are other issues that remain to be solved.
Dinesh, what is your wireless adapter model and driver version?
