Live TV; Wrong position of subtitles

this is the same issue as I reported a week ago - no comments sadly

Pvr subtitle placement after upgrade

PVR subtitles are smaller than before the upgrade to Isengard and they are now placed a bit up and to the left?!? I just tried Isengard on my Ubuntu laptop and there it works as expected. Also changing resolution does not change anything, and subtitles on movies and tv-shows works as normal. How can I downgrade different packages for testing purposes?
