7D vertical banding and HDR

I have a 7D, shoot RAW and process with DxO into DNG's.

Recently I have been doing some night skylines using Photomatix and am experiencing a problem with vartical banding.

Now I have been shooting with the 7D happily for well over a year and this banding issue has only cropped up since I started using Photomatix which is pretty heavy PP (particular on the more intensive processes like "Painterly"). It is very noticeable (no pixel peeping) appears in smooth dark & light areas like the sky. My subjects are different now and I shoot with a tripod and lower ISO's

Some people have reported a problem with low ISO's. I have done some test shots and it is definitely very bad at ISO 100, slightly better at ISO 200 D+ (highlight tone priority on), and better with ISO 200. (I can't really go above 200 because I am doing long exposures)

Does anyone have any experience with this issue - is it a fact of life with the 7D or is it limited to some copies?

thanks for any info
