Hi all! I realised that when streaming BBC News from: http://www.bbc.co.uk/news/10318089 in my Macbook Air Late 2010 the image flicks. I updated all software (both mac os and flash player). Then, I went to the local Apple Store and same problem in every single machine. Though everything is fine in my girlfriend's Macbook Pro 13 inch!!! Any ideas? Cheers!
