Nikon Coolpix L310 focusing problem?

I'm having a problem focusing the picture when i take them mostly at night with artificial lighting I don't do anything different then I do when I take them in the day, where it rarely happens.So I don't know if there is anything I'm doing wrong or if there are certain settings I need to change. I love the camera and got it for Christmas so I'd love to just fix the problem.

Is a SONY Camera best for removing Jitter & Distortion?

I have a Nikon Coolpix 4100, and the Pixel count is high, but you can read the reviews. Images are grainy, and video is shaky and distorted.

What is a good recommendation for (or what is the best CMOS?) the best CMOS to control stability, and never worry about grain? I want to be able to take low, and high light level images, and video. I am a perfectionist, and everything is played back on Sony XBR TV's, and any distortion is an eye sore.

Any thoughts? I would like to stay below $600, but will go to $900 if I have to. I want pictures and video, and want perfect color accuracy with as little distortion as possible in that price bracket. I dont mind if it is large or small. I prefer small, but I need "Quality". I need quality images from at least 5 feet to 100 feet with minimal noticeable difference in PQ (Picture Quality), if any at all.

Please, do not mention any forums for me to go. I need a great camera recommendation from someone who "knows".
Thank You!

EDIT: For an idea of the minimal quality I'm looking for (if you're into dance… ) search Youtube for "Adele Chibi". Though shot in 720P, I see minimal distortion compared to many 1080P Video Cameras.

How to get my Nikon Coolpix L810 to perform better?

I paid $207 plus taxes for my Nikon Coolpix L810 camera and I'm getting the feeling that I got ripped off. When I take pictures without the flash, the majority of the time they end up blurry and out of focus. Even when I hold my hands almost perfectly still and whatever I'm taking a picture of is still too, the picture is still of poor quality. I'm not sure if it's because I am using the camera on the wrong setting or if the camera just sucks altogether. If you have experienced using this camera before, please let me know what your experience was like. What do you recommend I do? If I did get ripped off, what other cameras would you recommend?
