I'm not sure where you're referring to when you say export format, but in Control:Mac settings I can see a button called "Export Format", but in this there are only 3 main options:

- None
- MP3
- AAC

Whilst I was unsure which to select, I'd read somewhere that selecting "None" leads to nothing exporting, so chose to use highest setting of AAC (I'd already done this before, as well as tried "None" option).

Separately, I realised that I had not tried turning off my MC200 and turning on again. When I tried this, everything started exporting automatically as soon as it started. My whole collection is now exported, but it's also worth pointing out that I imported a new album yesterday and it has not exported this yet.
