Is the scope's 10X Magnifier on? I cannot tell from the video. That would make the gitter of the sound card look 10 times worse than it really is.

I got this oscilloscope a few days ago. I put up a 1 Khz sine wave (from PC sign wave gen.) to test it. But my sine wave won't stabilize. When stopped, it dances around a bit with a slight pulse. All this makes it difficult to make a proper frequency reading. It's a great scope except for that. Does anyone have any idea what the problem is?
Here's a video link
