Dolby E is just a data stream created with guardbands around the video frame boundaries.
So it’s PCM uncompressed data.
If you capture as PCM (MXF is fine) at 24 bit you will capture a data stream. You can’t play it back and hear audio but you can, in theory cut it on video frame boundaries and lay back to tape.
It’s imperative that it retains sync with the video frames of course.
There are plugins that let you decode the data stream to discreet audio channels either in software or in hardware externally.
The safest way is to decode the Dolby E on the way in to your Avid and capture 5.1 audio (it could be 8 channels in all)
Then frmae rate convert and the re-encode back to Dolby E. that can all be done in software but make a mistake anywhere and you can corrupt the stream.
