So, the solution for Win7 is to use double quotes and escape all internal quotes.

Cool, that works great. Thanks! Might want to add this bit of info to the documentation. By the way, same issue exists and solution works with Windows XP. Alas, I've just never been able to capture the whole error message in XP as the batch file terminates directly after the first calibredb run (known issue, problem with Windows XP so can't fix so I just use the start workaround).

Funnily enough, I tried:

--display="{'date_format':'MM/dd/yy'}"

and:

--display='{\"date_format\":\"MM/dd/yy\"}'

I thought I had also tried:

--display="{\"date_format\":\"MM/dd/yy\"}"

but apparently not.
