Okay, look... since you have no control over the topic title (only the OP can change it), I suggest re-posting this exact information in the tech forum and using a specific title like "Problem rendering in-game movies with ATI 64-bit Win 7".  Often detailed titles like this will catch the eye of folks who have a similar/identical configuration.
Since I cannot emulate your problem (I use XP SP3 and a much older ATI card) I can only point you to former discussions until others in the social community reply who may have had success.  The second link (mine, above) seems to be the most helpful for you since it applies to the ATI card operating (or rather, NOT operating) in a 64-bit environment and the issue of not being designed to properly interface with the 32-bit dynamics used by NWN.  I have read about folks 1) rolling back Catalyst versions until they found one that worked, 2) installing a non-Catalyst legacy ATI driver, 3) disabling UAC... basically redesigning the graphic interface just to get NWN to play with newer hardware and OS (goes back even to Vista).
If I were in your situation, I would try the most direct and least invasive solutions first (like the SafeMovie & simplemovie adjustments) and then consider the more complex fixes.  You may end up re-installing NWN multiple times should the stability be compromised with any of the fix experiments.
The only other suggestion is to contact ATI and try to explain what limitations have been encountered with your configuration trying to use their product, perhaps even furnishing the link documenting others who have experienced the same problem with their ATI cards/drivers.  How responsive ATI is (I think it's actually AMD that services the products nowadays) to help you is another issue altogether. And if it was installed as OEM, a card manufacturer will usually redirect you back to the machine vendor.
The_Krit posed a question in one of the problem threads that seemed appropriate. "How badly do you want to view the movies inside the game?"ÂÂ
