Can ETH still be witdhrawn from theDAO?

I never bothered to withdraw my funds from the DAO after the fork, because I thought it was a very low amount. Turns out it was way more than I thought.

Can I still withdraw that?

The wallet I used was a mist "contract wallet". I have the key of the account that controls it.

I found the withdraw contract (https://etherscan.io/address/0xbf4ed7b27f1d666546e30d74d50d173d20bca754#code), but I don't know how to call the withdraw() function "from" my "wallet contract". In fact I don't even know how to import that "contract wallet" into metamask or MEW or anywhere else (I can import the controlling account into both).

Are these wallet contracts still a thing?

Any help appreciated.

I will be generous to anyone who helps me substantially in recovering the funds.

UPDATE:

MAJOR SUCCESS: I managed to transfer the DAO from that dreaded legacy mist contract wallet to a "normal" account based wallet by calling the wallet contracts execute() function instructing it to call theDAO transfer() function.

I haven't redeemed to ETH yet because I'm considering to sell some DAO to those who are collecting.

I had tried to use the withdrawDAO's witdhraw() function (after approve()ing with theDAO first, which worked with enough gas), but this persistently failed ([out of gas], [invalid jump destination] while still eating a lot of fees. It's not clear to my why.

UPDATE2:

So I withdrew the largest part of the DAO to ETH now. I have some DAO left to sell if anyone wants some?

Thanks for everyone's help!!!
