Hi Noah,
Hi Definition simply means that it can do up to 1920 by 1080 pixels.
All the same camera techniques apply as in SD cameras and still cameras.
It is good to experiment with a new camera under a variety of conditions and see what the results are. Then you know what looks good or not. You can also tell us what conditions you shot under so we can give detailed help.
I am not an after affects expert, so I will discuss items in the camera that could cause this.
Generic help is that graininess is often a byproduct of the camera internally boosting its gain to make a dark scene bright enough to record. If you have the data display turned on, and you see that the gain setting is about 6 db you will start to see graininess. If it is about 15 it will be very noticable
Try shooting in bright light (with ND filters off) and use that as your baseline. If that is still grainy make sure the camera is recording in HD. If it is, then make sure you are bringing to after affects correctly

It sounds like a trip to sony repair.
If you don’t get sound in, I would check the audio settings on the left to make sure they are set to correct inputs, and if the volume is on manual control, set the volume to the middle.
Then I would check the setting on the right side that determine line or mic or phantom mic settings.
For the output, there is the volume control, unmarked on top of the camera with the up and down arrows.
It sounds like you have tried all those settings. For both input and output to change settings at the same time sounds like something inside is broke.

I don’t have the 70 model, but I can offer some insight to your question on why the blurriness is worse at low light.
The focus sysmtes in these nxcam models seem to all work on a feedback look that tries to get the sharpest edges, particularly vertical edges.
When the sensors are working in low light, they have video noise. Noise is where the sensor can’t quite tell which of several colors or shades it should be, so it changes between the range that it thinks it is.
The focus system sees the sensor output changing and things that it needs to adjust the focus, so it trys to do that.
This style of focus system will always be worse at low light.

I must have started a second thread because I also had uploaded examples and feedback from sony techs saying that is as good as it gets.
I actually bough the nx70 and tried it out for a couple of days before sending it back. The nx5u is bad, but the nx70u is worse.

I feel quite chastised for my hesitation of upgrading to windows 7.
Steve, your concept of having the ability to keep the old one in parallel has given me the secret that I was looking for.
Thank you very much.

The reason is I am collaborating with 4 other editors. If one upgrades, we all need to upgrade. I am too busy at this moment to do all the migration of the million support apps and drivers which an upgrade to windows 7 entails.
I will have time near new year to migrate the computer, but makes intercompatibility an issue for several months.

Oh,
Now I understand. You are pointing to a GPU emulator. This is a SDK which includes the driver that should make the TrueBlue think it is talking to the GPU, but really talking to the CPU.
I will see if I can figure out how to use this.
By the way, I talked with the Sony Customer Service Manager who talked with TrueBlue. They changed their website. Now the list of Trueblue requirements clearly says GPU required.

If you are simply archiving and not doing any editing at all, then just stay in the original mpeg from the camera and burn it onto dvds.
If you will have to edit at all, to put chapter markers or names of people speaking, then you will have to edit.
I always render to avi first, which is uncompressed, then in DVD architect I select the compression ratio. The reasons I go through the extra steps are:
1. If my project is just a tiny bit too large for the disk, I can compress a little more and squeeze it in.
2. If it is a rough cut, I compress a lot and fit more onto a single disk for a client.
3. I have the avi master if later I want to create something lower resolution for say the web.Because architects accurately predicts how large the end result will be, it is easier than trying to guess the compression in Vegas.

Brad,
Recording and producing dvds are two different items.
You can record in anything you want.When you render, render as a standard avi sd format from the timeline.
Then you compress it into mpeg for the dvd. You can compress more to fit more length onto the dvd at the expense of details. Or compress less to qet the best quality.
Normal compression from avi to mpeg is 6mbits for “DVD” quality.
4mbits compression would get you vhs video quality, and 3mbits would get you lp vhs quality.If you have mostly static images like scenery or powerpoint the 3mbit would not be noticed, but any other time and it would be a degradation.
The second variable you have, is to use double layer DVDs. yes a standard single layer is 4.7gbyte, but a double layer is 8.5
When I put content on DVDs, I do it at 6mbits and get about 2hours 40 minutes on a double layer dvd. About 1 hour and 30 minutes on a single layer dvd.
