I am also using Davinci Resolve as a SE replacement. I don't know a way to use an SE EDL.
I am trying to find a convenient way to use my SpeedEdit HQ renders in Davinci since it doesn't like .avi files and the Newtek codecs don't work.
Only solution I can think of is to convert my HQ files from SE into a series of stills which can be loaded into Davinci Resolve
