Dust or Defect on my sensor?

Just (24 hours ago) picked up a brand new Canon 60D. If filming HD vid at 25 or 25 fps in 1920x1080 there appears to be a red pixel or 2. When upload to my mac this red pixel is still there, so I'm ruling out a fault on the body's LCD screen. Also present if taking Raw image, not present on jpeg.

I'm only noticing this when filming/snapping with the lens cap on to achive the black background on which to check for such a small imperfection, i.e. take a normal pic or video and there's too much going on to pick this out.

In brief, it's only there with the highest resolution settings, is this significant?
