I have PowerDVD 16 (or 17?) on my HTPC because MC can't show Blu-ray menus, and sometimes I want to view the extras on a Blu-ray, which requires the menu, but I don't want to rip the extras and save them to my HTPC.
It is very annoying software, particularly as I use it rarely and every time I do it needs an update, and usually more than one, before it will play a recent Blu-ray. The latest update wouldn't even play a Blu-ray while DVDfab was running.
If you aren't going to use it but have installed it, uninstall the Media Suite 10. That is old, with the current version being 15. It will give you no end of trouble and propose upgrades continually. I installed the Media Suite (7, 8, or 9) that came with my Pioneer and it was near useless and needed special updates just to play any Blu-ray. Better to buy the latest version of PowerDVD, but at one of their discounted sale prices, rather than keep that rubbish.
Strange that you Pioneer drive died, although I guess it does happen. My old Pioneer BDR-208EBK drive is still doing fine, and I don't think it was much of an update from your BDC-207DBK.
