Thank you for your detailed reply.
Yes it does seem to be down to the control point but I can't identify any differences in my tagging for those that work and those that don't. I will explore it a bit deeper and contact the control point developers about this issue.
Regarding the point about log errors, I googled the albums concerned and found that the release dates for the albums were different to the ones I had tagged. In a couple of cases I had put in the original LP recording date rather than the CD release. When I changed the dates the log showed no errors, so is it the case that MinimServer is querying a database like Musicbrainz and reporting an error if there is a mismatch? It seems to ignore other situations where no database is available to query like an audiobook, but it did report an error for one audiobook I compiled from R4x where I had failed to put anything in the year tag, when I put 2014 in it didn't report an error so it looks like it didn't like the field being empty.
I am grateful for your help.
