I too ran into this problem when installing the latest WHQL drivers from Nvida, 185.85, and Power DVD 7 stopped working with the, drivers are not compatible error while running Windows 7 RC.
What I found more irritating is the fact that I got a crappy 3 year old player that doesn't run the hardware I purchased adequately enough from LG and to get software that will, will cost me 59-99 dollars.
Power DVD 7 is quite clear not to meant to be the best Blu Ray player, most likely the first player created to play the HD formats by Cyberlink. This to me was evident when after encountering this error I gave Power DVD 9 a shot and noticed that with 7 I would encounter stuttering and even freezes while watching Blu Ray's this is gone while running DVD 9.
Haven't had an issue with DVD 9. I don't like the fact that inadequate software was bundled with my Blu Ray Drive, both a fault of LG and of Cyberlink. Cyberlink for not offering a better deal to LG for better software to be included with there players or even offering a better upgrade options for people who purchased Blu Ray Drives from LG for better and more efficient software.
So now I will be using my trial of DVD 9 till that is up, then I will be trying the Trial of other Blu Ray software and see which one I like out of my options.
