OK, trying to do this but if I start 4 mins in and trim 1:20 off end I get different length for audio and video.  Any advice.

Maybe just a display rounding problem. Video is referenced in frames, audio in samples. Carl will probably comment on this. Never used the trim feature with split video/audio content. As this is only for testing, small sync issues shouldn't be a problem, as long as it is correct for the full length version.

That will be the problem - when you insert video and audio separately, you need to trim ALL files that need to run in parallel with the same parameters. If one is left untrimmed, DCP-o-matic will create a full length DCP with the remaining trimmed audio and video tracks padded with silence and/or blacks.
