I think I've sorted out the problem with the DNG 1.3 version not doing the bad pixel correction properly in ACR / Lightroom.

Revision 1805 should work better (fingers crossed).

I've also removed the bad pixel opcode values 1, 2 & 3 - so only pixels with a value of 0 will be fixed.
Having gone back over all my test files I can't find any with non-zero values for bad pixels (when looking at the correct active area only).
The issue with the IXUS220 having values up to 16 seems to be wrong (my bad) - hopefully someone with an IXUS220 can test this and see how it works.

I get bad pixels with DNG 1.3 + trunk1805 + Canon A590is 101b
All fine with DNG 1.1.

I use Rawtherapee and IrfanView with DNGs.

Thanks for testing, it appears that only Adobe products currently support the DNG 1.3 specification at present.

To confirm:
Two tests with trunk1805 + CHDK DNG features 1.3 and 1.1 - SX130IS.
-In Adobe Lr3.6 post processing  - NO bad pixels with both DNG1.3 and DNG1.1
-In Photomatix Pro 4.1 postprocessing - with DNG1.3  Bad pixels exist... see picture.
 With DNG1.1 -No bad pixels...
Thanks to philmoz for this  DNG Feature.
