Here are patches from vdr-xine 0.7.6 that I modified to apply to xine-lib and xine-ui snapshots from January 5th. They work fine.
Btw, why the Xine developers haven't applied those patches yet?
I've not done anything besides trivial bits because I don't know the affected code anywhere near well enough. Others haven't due to things like time constraints or Somebody Else's Problem.
All that I can reasonably suggest is regular postings of the patches to xine-devel or the creation of an appropriate tracker item.
