Yep...select clips on your A/C,..and play 'em back on the screen.It's just not smooth. Yeah, I guess skipped frames would be a good way to describe it. It doesn't seem to be an RF issue. But as I said in another post, I've encountered this in Android devices before after flashing the ROM, so I wouldn't be surprised if it clears itself up.
I've only seen it when flying, mainly when panning. I wasn't aware that the SC could do playback (playback of what?).
