Thanks Andrea,  I will keep an eye on the codec driver and send 
important fixes on this codec to the maillist.

And also Kaiheng is work on HP machines, those machines need this 
patchset too, Kaiheng and I will work together to make sure the 
important fixes for the codec will be sent to the maillist.
