There are only a few things I've seen that required anything out of the ordinary when or for burning discs... One was the Old Windows setup discs, where it was a bit tricky to make them bootable after adding in service packs. And years ago it could be iffy burning a video DVD, until Everyone figured it out. The only old gotcha that's still [maybe] around is if you want to burn a dual layer video DVD, which is [& has always been] best done with the free ImgBurn [imgburn[.]com]. Otherwise most any burning software should do nicely, at least as long as you just use it to burn discs, and don't expect some fancy DVD or Blu-ray video disc authoring. And for that BurnAware will work just as well as most other apps -- it's just a matter of which one you personally like best.
That said, I would quibble about the MSRP of $20... it's admittedly been rare the last couple of years, but on sale for less than $30 [3 years ago I paid $12] Nero Ultimate [full, not subscription] includes so much more that there's just no comparison.
BurnAware Premium installs pretty much wherever you like -- the comment saying it wouldn't / couldn't on today's GOTD page was obviously wrong -- taking up about 40 MB in the program's folder, with a burnaware.ini file in c:\Users\ [UserName]\ AppData\ Roaming\. It adds a bit under 90 new registry entries, including adding it to the context menu & autoplay.
