Hot Pixels remapping - built-in Camera ?

I remember once reading in POTN a post referring to a Canon camera built-in feature of remapping Hot Pixels, immediately after selecting "Sensor Cleaning" option in the menu, and then activated by a power-off/on sequence.

Is this really working ? In which Cameras [rumors have it on 5D only] ? Can it be actually verified ? Was this ever confirmed by Canon as being an official firmware feature ?

I’ve never heard of automatic hot pixel remapping..
Are you sure that it was not about appending dust delete data to the picture?
That feature does exists on 40D (and 1DMk III if I’m not mistaken) and works quite well.

I don't worry much about hot pixels. Lightroom seems to take care of 'em automagically. Kinda nice actually.

Yes, I'm almost positive that someone in POTN has mentioned it as automatically done for Hot Pixels after a Sensor Cleaning activation. But then again, I'm not sure it was ever proven.

roli_bark,
You do know the forum has a search function?
Anyway yes it does seem to work here are some link to this forum where others talk about it here, here from Hermeto, here, and here and this is just some of the many that can be found using the search function

It is interesting that Canon doesn't confirm that as an official feature:

i'm not too certain about hot pixels (ones with higher than normal sensitivity), but sensor cleaning does solve dead pixels (pixels that return the same max value or min value no matter what what shot or what iso it's in. taking a blank shot and then doing a sensor cleaning function (lens still on) seemed to get rid of a nasty red dot that showed up at iso100. as for hot pixels, lightroom does do a great job at it (until 6400 underexposed a stop), but you can get better results from subtracting out the pixels in photoshop (take a shot with cap on, then open in photoshop, invert, multiply on top of another shot).
