[mythtv] Comments requested on two bugs

[Peter Bennett]

There are two bugs I have logged, with my recommended fixes.

https://github.com/MythTV/mythtv/issues/739

I am proposing removing the use of std::move. The different ways of 
accessing QString, and how the memory is managed com into this. I ran 
some tests of the solution, and I could not find any memory leaks. If 
there is anything wrong with this approach please let me know.

In one field the API is returning different values in xml and json. The 
fix may affect users of the xml API. I believe we need to fix it anyway.
