What controller is the drive attached to? Right click the drive drop down box and select 'family tree'. Close the box that comes up and then copy + paste everything from the log windows please.
OpenCandy is a DLL that runs within the context of the installer. It isn't something you have to 'get rid of'.
Have a look at their website and learn what it is.

What are you hoping DAO would give you? It doesn't actually exist as a write type, it's SAO, PACKET, TAO and RAW.
M-Discs are burnt the same way as normal discs, it's the hardware that has to support them.
What drive do you actually have?
You've connected it to a controller running dodgy drivers that mess with the device identifier. Either get it off that controller or install some updated drivers that don't mess with it.
The 'SATA' part of 'SATA HL-DT-ST......' should NOT be there.
It may be that you have this drive - 'GGW-H20L', in which case, there's a much newer firmware available for it. That may fix the issue burning those discs.

Standard and Advanced input modes are 2 totally different things.
Adding files / folders to one mode doesn't mean it's then visible in the other. There's stuff you can do in Advanced mode that simply cannot be done / represented in Standard.
Now on to the conflicting files issue... you must be adding file from 2 folders that are ending up in the same folder on the disc.
i.e. if you drag 'c:\folder 1\file 1.txt' and 'c:\folder 2\file 1.text' over to the Source box in Standard input mode, both of those files will end up in the root folder of the disc - which of course can't happen as they have the same name. The 'Preserve Full Pathnames' option will get around that by recreating the *entire* folder structure of those files on the disc.
You could also just add folders to the source box rather than files, that's easier to manage and is really what that (basic) standard mode is for.
Advanced input mode makes it easier to see where things will end up on the disc.
I've never heard of AFA so I don't know the dye / MID the discs actually use.
Of course just being expensive doesn't make them any good. They may use a cheap dye and just have an over inflated price label stuck on them.
Try them in some other drives if possible and see if any of those can initialise them. If one can, please post up all of the disc info from the box on the right when you're in Write mode.
Your drive isn't in the 'Ready' state.
Notice the message in the status bar at the bottom of the main window.
You'll have to try with some different discs.
