To enable the WD DLNA server you first have to update the firmware. Follow the instructions in the link below.

You won’t see a “switch” of choice between the two servers in your dashboard. It’s a design flaw in the interface which many folks have documented on this site. Follow the instructions in the link above, and once you make the change by uploading the file all you will see is ability to enable the WD DLNA server - just like all you can see is the Twonky server now.
It’s not very intuitive, and hopefully the wizards at WD will change this oversight in a future firmware update. It should be easy to select between different options, but it’s not right now. You will only see one or the other.
As to connecting your MBL directly to your laptop, or any other machine, I’m pretty sure you can’t. If I’m wrong please let me know so I can move bits around faster too…
You can only access MBL via your network. You might try connecting with wiire as it seems a tad bit faster when transferring data, but be prepared to have your patience tested when transferring multiple gigs of data. It can take a while, and the problem with data transfer rates is well documented within this community.
