Actually the workflow #1 I suggested should work for you..
The problem right now is that there are no reel names (aka tape) in avid, and Resolve needs to see something there.
The solution if indeed none of your clips have reel names is to give them a generic one. (“temp” for example) See above for how to do that.
Export a new version of your aaf (this one will now have generic reel names for all the clips)
Import the aaf into resolve and tell it to import media. Either way it will import a bunch of clips, but depending on your situation it may not actually connect to them. At that point check the media pool to see if the imported clips have reel names. Hopefully they should. If not, right click, set reel, manually type in “temp”.
That should be enough to make it work. In my experience, resolve is in fact using the clip name in the aaf (the reel and TC are bogus.)
