Also, I saw a video of Rockbox playing video on the Sansa Clip, and I saw these weird dancing dots and was wondering if that's like that in real life.

That video is really what it looks like.  Thats about as good as you can do on a monochrome display.

The "dancing dots" come from the fact that we emulate 127 levels of gray on basically monochrome display. It is done by fast alternating dots pattern which yield desired mean intensity. On lcd displays this looks somewhat acceptable as the response time of the display is quite long and consecutive dot patterns bled together. The clip however uses oled display with very fast response time so you see all intermediate patterns. There is little we can do about this.
