I have long kept my old version of QT, 7.6.2 (515), because of all issues with newer versions and incompatibility with Sony Vegas. I always decline the updates popping up.
Now since Magix stepped in and gave us Vegas Pro 14, which at the moment in my machine seems rock solid, is it safe to upgrade QT now or is it still best to keep the old?
By the way, I had given up on NB Titler 3 Express that came with Vegas 14. It never worked and didn't have enough tweeking features. But in a recent job I did I was actually able to get good use of it making some quick titles and lower thirds. I am happy the customer didn't ask for any changes in colors etc in them as it wouldn't have been possible to do in NB 3 Express. Anyway, a few of the presets were usable as they were. :)
Cheers
