I know you didn't really think she'd take you back if you copied the MiniDV tapes, so I won't even go there.
There is nothing you can do to control her, convince her, or change her.
Keep focusing on YOU. Keep working on GAL activities, keep working on your 180's, keep working on "acting as if".
Get your own lawyer and protect yourself, don't work with her lawyer directly. If she is committed to divorce, it will happen, and you cannot change that.
That does not rule out reconciliation. Things might get worse before they get better, but it's not over until you decide to walk away. All that matters in the end is what changes you can make, how you feel about yourself, and what you decide to do with regard to wanting to reconcile.
