I'm wondering if just an upgrade to Windows 7 Home Premium would solve the problem with choppy and frozen video on my PC from video I imported from my new Nikon 3100 digital SLR. Nikon said, "This happens whenever the computer does not have the proper drivers to playback high definition videos". And they said a fast processor and a lot of installed memory- but even that may not be enough because there are "...a lot of factors that determine system performance". Or would it be better to buy a new computer. Thanks, David in Milwaukee

That's strange. This article- Dell Inspiron 531s Review & Rating | PCMag.com says that it comes with 2 Gb of system memory and it also says it has discrete graphics. Later on, it says that the graphics card wouldn't be available until after Novemeber 1, 2007. So, I don't know what he has.

If he doesn't have 2 Gb of RAM and a discrete video card, he's fighting a real battle with video since the integrated graphics is probably sharing operations (and memory) with the CPU.
