I was quite happy with the latest official Mele firmware except blank screens on Youtube/Flash/video (for example in MxPlayer).
A new firmware has been released to fix this issue, and to enhance some other things:

Additional note: there is an issue with Windows 7 PhoenixCard (thanks to JP for pointing it out), see my next post.
