Do they only show up at slow shutter speeds or fast ones too?

Edit: btw Winkle both those links you showed me contain a virus that my NOD32 caught.. you may want to use a different host.

Sorry, did not know that. Thanks for the heads up, I will not use that host again.

Pretty common with DSLR. My Rebel XS has two apparent ones. Try taking a picture with a long exposure (30 sec), ISO 400+, with the lens cap unremoved so it is black. You'll see a lot of colored stars. If you exchange the camera, it will probably have some to start with or they will appear after a few weeks. Lightroom automatically detects them and hides them by extrapolating the nearby pixels.

yeah pretty common which is disappointing. If it is happening between ISO 100-400, I find it is unacceptable for a new camera. This usually happens more frequently at higher ISO. If you use any Adobe product to convert your RAW files, it will automatically fix the hot pixels for you. I use lightroom so I don't have to see those horrible pixels and worry myself by pixel peeping.
