age is used to skip drawing of MBs, it is set by the get_buffer() 
implementation, and simply means the the number of get_buffer() calls since 
this buffer was returned the last time
thats usefull because if a MB is skiped more often then the age of the frame 
then it is still in the buffer (assuming only simpe IP frames are used, 
otherwise its a bit more complex) and so it doesnt need to be copied from the 
previous frame
