Can I get VinylStudio to address a Mac Remote Disc which is mounted? I can see and manipulate files on a remote disc from Finder, but in the VinylStudio Burn CD options, it does not appear in the CD/DVD drop down list.
No, sorry, that is not supported by Apple's Disc Recording routines. The way to do it would be to run a copy of VinylStudio on the remote machine, opening the collection on the main machine across the network.
Do not have two copies of VinylStudio open accessing the same collection at the same time - that is dangerous.
