I have not noticed the first situation you describe? Can you provide more details on how it is causing a problem?
Regarding the second problem, that one is simple, you are moving the camera as you press the button to stop the recording. I know you don’t feel like you are, but you are.
If you use a tripod with a remote controller you won’t see the movement at the end of the clip.
You have to practice very hard to squeeze the record button to end the clip without moving it until the record light is off. Have someone videotape your handheld shooting and you will see yourself doing it.

Color balance. That could be a long long discussion.
It sounds like the number it tells you in Kelvin when it does the auto white balance is not accurate, or rather, not using the same calibration as when you set it manually. If I were you I would try this experiment, then find out which color temperature gives you the same picture tone. Then mentally use that offset number when you set it.
This error can easily happen if you are shooting with LED lighting, or possible two different colors of light, like daylight plus fluorescent.
Color in degrees Kelvin assumes black body radiation. In other words, a graph of energy vs frequency (which we interpret as color) would look like a bell shaped curve. Remember the curve in school.
This is true for sunlight and incandescent lighting. Your eye interprets the highest point of the curve, the average, as the color temperature of the entire light, even though other colors are present.
If you have LED lighting, it does not produce a bell shaped curve of light. It produces two spikes of light, usually one yellow and one blue. The automatic white balance tries to look at two spikes of color and guess what the average is. The average is actually between the two spikes. There is no perfect way for it to average two peaks and give you one answer that represents a bell shaped curve. So, the designers had to put in some kind of firmware to guestimate this.

Try to capture the footage without using the camera.
If you have an sd card in the camera, remove it and plug it into your computer or an sd card reader connected to your computer.
If you are using the NXCAM storage device, remove it from the camera and then plug a usb cable from your computer to the storage device.

Sherman,
Thanks for jumping in, I was quoting your comments to me about my own cameras.You guys, I recommend Sherman at VideoOne Repair. They do a good job and will talk with you on the phone beforehand so you can know all your options.

Thanks for the background.
You have set the switches up properly to match what your marantz has been recording.
Let’s defer the question about creating mono in the editor, since this should match what you have been doing.
You should be able to move the next step, which is figuring out how to get the audio from the video.
What I do is simply open up the raw video file in my video editor (Sony Vegas), then tell in to render as a wav file and it saves just the audio. An alternative is to use an audio editor that has the ability to open video files and extract the audio from it. I use Sound Forge for that.
Do you have a video editing or audio editing software that you are planning to use yet? If so, you should be able to test this by recording 5 seconds of yourself on the video camera.

The definition of the video file contains two audio tracks. The camera has two audio inputs.
When you say mono, to the camera that means record the same audio input onto the two audio tracks.
On the left side of the camera are two sets of switches for the audio.
First select which audio input you want to go to channel, or track two.
Then select which audio input you want to go to channel 1. If you select the same audio input to go to channel 2 and channel 1, then it is in effect mono.
A question I have is why would you want to record Mono. Assuming you are going to edit the footage, if you record stereo, then convert it to mono in the editor, it gives you much more flexibility.

Here is what it looks like to me.
There is an antireflective coating on the face of the screen. It is known to wear out and looks exactly like you show. There is no way to fix it.
You can have it replaced, or just ignore it.
I assume when the screen is on you can see the image.

Well you can recover until something else is recorded on top of it.
If it works for a 64 but not the 32, it is because you recorded the new material right on top of the spot where the original was. Or at least where the index was.
The only other idea I can give you, is to send it to a professional recovery place. It won’t be cheap, and they won’t guarantee their work, but if what you lost is that important, that is your next step.

You have to use the software that Sony gave you with the camera.
When the camera breaks the files into the 2 gig segments, it stores information as metadata in the folder.
If you use the software from sony to capture from the storage device, it automatically adds the missing audio as it joins the clips.
Do not simply copy the mts files from the sd card, or you will never recover the dropped frames.

I can tell you how to take it off.
the shiny metalic insert has a lip that folds down over the heavy metal holder.
with one finger of your left hand, push the insert away from the metal holder. With your right hand and a small screwdriver lift the lip and allow it to go the opposite way.
Once you slide off the insert, it exposes a screw to allow you to remove the metal holder.
