> 1) the "author sort" field on libprs500 is not used (only for libprs500 GUI)
That's a bit odd, as surely there's some reason for having the two fields in the first place?
> 2) author data changed using lrf-meta is not used if using libprs500 to put the ebooks on so ignore using it.
Remember libprs500 stores it's lrf 'files' internally, so I expect you'd need to re-import the modified file before writing it out to the device?
(My problem is that my corporate laptop has a locked down version of McAfee that results in libprs500's USB scan taking 100% cpu for minutes at a time, so I've gone back to just copying the file directly to the USB device and using the Sony Connect software if I want to setup collections. What's really annoying is that in practice, McAffe's been useless & failed to detect a real virus [Skype virus], so I'm also running AVG, as that did!)
