Help needed with my new webcam

Hi guys,
I finally took the plunge and got myself a webcam which was specifically designed for use with a Mac with an OS later than OS X 10.4. It is Plug & Play and works via USB 2.0.
Here is a link to the actual webcam that I bought .......

Mac Webcams -

There is one very important bit near the top where it says, "Built-in Microphone for Mac" and another important bit near the bottom where it says that this webcam is suitable for Snow Leopard.
There was nothing else in the box except for the camera with its USB lead.
I plugged the lead into my Mac Mini and the infra red lights came on on the front of the camera but nothing appeared on-screen to say that a new device was installed. I tried a few buttons and eventually got to iChat and my ugly mush showed up on a window within my TV screen. The picture is perfect. You couldn't wish for any better. It is crystal clear and when you move, it's like watching a TV picture.
Sound, on the other hand, is a different kettle of fish.
I can see a "progress bar" kind of thing under my image and it moves up and down, in green, as I speak or clap my hands. The snag is that I can't find a way to record my voice and image and then play it back so that I can check it for quality. I found a bit where it says that when using iChat, I can ask the other persons permission to record a conversation but I can't find a way to record and play back just me.

Does anybody have any ideas?
Cheers,
Steve

Moved. Does not belong in "Switcher". Please read forum descriptions prior to posting.

If you are using Snow Leopard, you can record with QuicktimeX. Just open the Quicktime player, and choose File->New Recording.

Lol just got in there before me with the Quicktime suggestion ;p

Thanks guys.
I'll try that now and see what happens.

Keep us posted pal

OK, I must be doing something wrong here.
I can get the Quicktime bit up and running and I can record and play back my waves and head shaking. That side is perfect.
But I just can't seem to get any sound or even any kind of indication that sound is being picked up as mentioned in the opening post.
My guess is that there is a setting somewhere to change the input device for sound but I'm so new at Macs that I just don't know where it is yet.
Cheers,
Steve

YES!!!!
I found it hiding in "Sound" in Preferences. How sneaky can you get?
Thanks guys.

Sorry, guys. One last thing.
When you change a setting on a Mac, such as the device used to input sound, is there a sort of "Save" button that you need to click to make the Mac remember the setting, dare i say it, like on a Windows PC?

From what I have seen, the Mac is smart enough to remember it on it's own. At least it has for every setting I have changed.
