Two days ago I rented a blu-ray of X-Men First Class and attempted to play it on PowerDVD 10. I got the message that the software needed an update and to go to http:/www.cyberlink.com/bdupdate/. When I went to that address and ran the updater it said it couldn't find any update software for me and gave me a form to fill out so that someone from Cyberlink support would contact me 'shortly'. As you can imagine, with a rental blu-ray 'shortly' didn't do me a whole lot of good. I found a download of the latest patches/version of PowerDVD 10, installed it, and it played the disc - except every 10 minutes or so the picture would break up into pixellation and stuttering for a couple of minutes. (With that regularity it's highly unlikely it was the disc.)
So now it's two days later and no one has contacted me from Cyberlink tech support. This is terrible customer service, especially for a software product that costs as much as a standalone player with more features.
Some time ago I tried version 11 and it wouldn't work at all, even for regular DVDs - when I posted the issue here all I got was the recommendation to update the drivers on my computer, telling me the Cyberlink people didn't have a clue. Since I didn't feel like spending hours and maybe days fiddling, I just went back to 10.
Between the bugginess of Cyberlink software and the poor support, plus the high price, when 10 is retired I'm going to buy a standalone player. Maybe sooner.
