Thanks Chris and Lyn.

Chris, as for the credit amount not being over the original charge
amount, are you sure that's an Authorize.net limitation and not one
imposed by the merchant account?  I have the same restriction on my
Authorize.net account and I thought it was imposed by my merchant
account.  I know there's a paper you can fill out to remove that
limitation.

I noticed there doesn't seem to be an entry for the last 4 digits in
your snippet above.  Is that meant to be set to mv_credit_card_number?

How many files did you modify to make this work?  I'd love to have the
same functionality.
