When I stream a video in iTunes from my PC (Windows 7) the image will transmit to the TV but the sound does not and continues to play on the computer. For the past two days I have been able to successfully stream via the wifi to tv with sound and video. However, today we had the audio problem, after doing the same thing to start it as the past two days. We also experienced this problem the first time we tried to use the wifi media connect but it resolved itself. I have updated the TV software and the wifi media connect software and the issue persists. Please help!

Thank you
