And even if they would be hierarchically transmitted, it would not be 
possible to receive them: The LinuxTV API as of today is not capable of 
selecting either the high-priority stream or the low-priority one - there 
is simply no field to select it. All it could say is whether there is 
hierarchy used or not.

However your patch is good and should be applied - it seems soon there 
will be good support for DVB-T hierarchical transmissions.
