Having had PowerDVD in various versions over the years, I downloaded the trial version of PowerDVD 11 weeks ago to review it for the eventual purpose of Star Wars on Blu ray. Since my trial version was set to expire before Star Wars was released on Blu ray, I went ahead and upgraded to the full version to the tune of something like a hundred bucks. I was otherwise satisfied with the trial version of this after using my other Blu ray discs for testing, so I had no reason to be suspect. Now that I've gotten (had for a week or so) the Blu ray versions of Star Wars, NONE of them play on my computer. They work flawlessly on my standalone Sony Blu ray player, but all of the discs in this Blu ray set will seize my computer up every time. Nothing in my entire collection of other Blu ray discs is a bother; they all play flawlessly on PowerDVD 11. Even Avatar, which stopped playing long ago on my previous version of PowerDVD, is now once again playing without a hitch. But not this Star Wars. Is anyone else having this issue? If so, what's the catch?
