--------------------------------------+-------------------------
 There are two version of DVBChannel::ReturnMasterLock in the code, the
 second taking a const pointer.  It then casts away the constness of the
 variable and calls a function that appears to modify the variable.  This
 is undefined behavior according to the standard.

 Removing the const_cast and changing the parameter to be non-const
 requires a cascading series of changes to functions and parameters.  This
 should be looked at by someone familiar with the DVB code.
