Patches applied fine against current git, but then building bombs with 
the following:

mhi.cpp: In member function 'virtual bool MHIContext::BeginStream(const 
QString&, MHStream*)':
mhi.cpp:857: error: cast from 'MHStream*' to 'unsigned int' loses precision
mhi.cpp: In member function 'virtual void MHIContext::EndStream()':
mhi.cpp:898: error: cast from 'MHStream*' to 'unsigned int' loses precision
mhi.cpp: In member function 'bool MHIContext::StreamStarted(bool)':
mhi.cpp:911: error: cast from 'MHStream*' to 'unsigned int' loses precision
make[2]: *** [mhi.o] Error 1
make[2]: Leaving directory 
`/root/rpmbuild/BUILD/mythtv-0.24.1/mythtv-0.24/libs/libmythtv'
make[1]: *** [sub-libmythtv-make_default] Error 2

make: *** [libs] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.dWQN5M (%build)

I'm by no means an expert on building, and in all honesty don't know 
what I'm doing 100%, but there you go.

Looking forward to this very much though!

cheers
