JPEG Size 12 X 8 NIKON L 120?

My Nikon L120 takes pictures at 4320 X 3240 pixels. When I want to resize these pictures the size becomes 12 X 9. But I want to resize picture to 12 X 8 or 6 X 4 without any damage to picture proportion. I am using adobe photoshop CS 3. Please guide me how can I resize picture to 12 X 8 or 6 X 4without any distortion.

I'm not able to open this video I took on my camera?

I have a Nikon CoolPix camera. I took a video thats about 11 minutes or so long. I try to play it on Windows Media PLayer and I get a message that says "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."
But I also have videos that are like 3 minutes long, and those play just fine.

How can I get these longer videos to play?
Added (1). I've installed VLC and it still will not play. I even tried Quicktime.It just won't play…
