try some other menu, like 'importing edl'? 

most likely autodetection was tuned for each NLE's native edl format (as far as i can guess) 

Ask on support forums if any possible imaginable way of importing this poor file failed... 

i do not think you need anything special, i installed opentimeline via 'pip' (python's own package manager), but you probably have proper package with dependencies on Arch?

Openshot/shotcut probably having their own code, and so is DaVinchi Resolve...

 Same errors with the new patch. Could it be that libraries or
programs for cmx3600 are missing in my system (arch linux)? I haven't
found any news about it.
In CinGG is reported correctly V or A, but the error remains. In the
edl made with the other NLE, even changing the incorrect A with V or
A/V the errors remain.
