SNR: Dmilligan and I already pointed that out. Use crop mode. No binning. Or wait for FRSP.
15 sec: At time of writing you have to live with that limitation.

And here we are running in circles: http://www.magiclantern.fm/forum/index.php?topic=5240.msg134066#msg134066
When you talk about DR you are actually referring to SNR (signal to noise ratio).
As dmilligan pointed out you have no proof of less DR delivered but shown what he admitted: Binning is deminishing image quality. If you want to compare DR you have to use silent pic in crop mode.

It has nothing to do with better DR. ML has a silent pic function right now but output is cropped/LV resolution. Full Resolution Silent Pic (FRSP) is able to use all the sensor's pixels.

Depending on your Lightroom version, after you export, it will only show the negative flagged original cr2 image. That is because you are in the LR develop mode. You have to switch from develop mode to library mode to see the new dual ISO dng in the same folder. It's a bug.

Audionut linked to this page already. There are two alternatives to try out besides lightroom. BArracuda and an postprocessing exe file.

Good luck. I,m on mac so can,t help you further.

cr2hdr: a post processing tool for Dual ISO images

--wb=graymax : set AsShotNeutral by maximizing the number of gray pixels (default)

Are you using the LR plugin from @kitcheof?
QuoteHow the plugin works:
Pictures selected to export are listed
Only CR2 and DNG files are supported (if file is not present, skip)
Each picture, one by one is converted with cr2hdr (with defaults or custom args)
if cr2hdr 20bit and --same-levels are selected, all pictures are converted in the same time
Picture is moved to subfolder
Picture is renamed with suffix
Picture is imported into Lightroom catalog
Label is added
Keywords are added (and created if needed)
Synchronize keywords with original file
Keyword Dual ISO raw or no Dual ISO is added to original file
Parse log file to fill metadata with cr2hdr results
Add picture to all collections
Keep or remove log file
Set the flag of the original file

Which cr2hdr version are you using?
Which settings in your cam?
You may upload an example and a processed output file. We may be able to run it, too and compare results.
