user2163: I have some old, low-light, pretty noisy DV8 video that I'd like to clean up. What is the best tool/technique to remove noise from low-light scenes?  
I also want to change the gamma correction to bring out the details - should I do that before or after I run any noise reduction?
I saw that Photoshop CS5 had some pretty amazing noise reduction capability, and that the new CS6 allows you to edit video, so my original question was "can I use CS6 to reduce the noise?"  But I'm ok with making the question more general.

user2155: Yes, as DragonLord said, with the extended edition.  
And assuming it's in a format (AVI, MOV etc. that Photoshop supports.
Once open, select Filter > Convert for Smart Filters.   Then run any filter, including noise reduction, and it will apply it to all frames.   Then Export > Render to Video.
