How can I use it without the tv tuner part?

If your has an A/V-out port and a cable that lets you output to a TV, you should be fine. If your computer already has a video input-many do, particularly ones marketed as media PCs-then you're all set: You can just plug the camera into your computer and turn on the camera.
If your computer doesn't have a video input, you can buy an inexpensive USB capture device for $5 to $10 on eBay, or a brand new EasyCap Video Capture Adapter for $15. The same device can let you watch TV on your computer, too, since the encoding hardware is the same-look for a TV-tuner-plus-video-capture USB adapter for $30 to $50 instead. You'll need to install the driver that comes with the device, but not the video-editing software. Simply run your favorite IM client; with the capture device's driver installed; the IM client should find your camera and let you use it as your webcam for video conferences.

I hooked up my Canon PowerShot to a desktop PC using a $15 video-capture dongle and simply ran iChat, selecting the video device as my input. I was videoconferencing within minutes.
With some cameras the audio will be sent along with the video. If that's not the case with yours, set your computer's audio input to its microphone.

This is a hardware driver problem.
The final version of Windows 7 has not been released yet, you most likely have the RC copy of Windows 7 (ie Release Candidate - final beta version just before official release) the RC is available to anyone to download and test.
The problem is that not all device drivers are avaiable and if you cannot get a Windows 7 version audio driver from the manufacturer's WEB site at this stage, you have to wait until it is available.

There are after market for mobile digital tv turner on sale on Ebay. You have to hook it up to the rear audio/video rca input on the brain. Goodlluck.

it's good

Olug it into audio input on mobo or sound card. IF that doen work, open up sound card and go through playback and recording stttings, ticking of line in and auxillary, and push levels up

I don't know about the frequencies being different or not, but to get to youse your TV you can use the tuner in an old VCR if you have one sitting around.
