Upgrading Cyberlink PowerDVD; which is the best and affordable

I have Cyberlink PowerDVD 10, and I got it with my blu-ray drive back in March. Obviously, there are have upgrades but I haven't gotten them yet, due to money for one thing (and a big thing), but also because I'm not very sure which is the better one. There is 12 Ultra, with a current sale for $45-50, but is that the only one? Is there something else, or is that it? I just want to make sure. Thanks!

If your version of PDVD works, there's no reason to upgrade IMHO. The Cyberlink website should list all of the versions available, so that's where I'd look for comparisons.

Sorry for the late post, but I guess I'm only asking because there are moments when I'm playing a DVD or Blu-ray that the movie (not the sound) will start to slow down for 2 seconds, then go back to normal, then after a while start up again. It confuses me why it would do that.

It's likely not the program. I'd suspect some background process would be a more likely cause. It would be hard to track down if it was though as you'd need to have the task manager or performance, or resource manager open to catch it. A Guy

How can I find out?

As I say, it would be difficult. Unless you keep the task manager, or performance monitor open all the time, so when it happens you'll be ready. You could look at the event logs if you note the time of the slow down. It's no guarantee the program isn't the cause, but it's not a common issue with Power DVD that I can see, so it's no guarantee updating will be of any help. A Guy

UPDATE 6/22 1:16AM
Okay, so I think I figured this all out: basically, last night, PowerDVD needed an upgrade/update, to which I didn't know about nor know what it did. But I did it, and it seemed fine. Played a couple of blu-rays, kept my start task manager up, and I think I know the picture/not the audio slowed: because if I want to play this thing without that problem, nothing else should be up (no IE, Firefox, etc), otherwise I should just expect it. The CPU usage was up to 100% using it and the external BD drive, and the Memory was going up that meant the picture was slowing.

I don't know if would still be problem, though. But I got my answer. Still don't know where to check on what it updated/upgraded.

BTW, did I mention the external BD drive? If I didn't, it was probably because I used the PowerDVD on just a DVD and still happened. Sorry if the BD drive needed to be pointed out from the beginning.
