Hi Keith
My understanding is that you cannot rip directly to a playlist.
You organise your music into playlists after it's been ripped and compressed.
It would be worth you checking out the brennan web site before you go any further with organising things on your B2.
There's a lot of good information there.
Some basic things to be aware of are - Sorry if this is stuff you already know:
Don't try to do more than one thing at a time on the B2. It can become corrupted or confused. e.g. Don't play music when ripping.
Don't rip more than 20-30 Cds at a time - Let them compress before doing more ripping. Done automatically when the B2 has been idle for a few minutes.
If you keep the web-ui open, the B2 doesn't go into standby so will not compress automatically.
Plan to backup your B2, sooner rather than later, to ensure that you don't have to rebuild it from scratch if a disk failure occurs.
Hope this helps.
Rob
