There are several ways to achive this.

1) Tags
2) Seperate Databases
3) Collection Numbers
4) Virtual Box Sets

1) Tags are the swiss knife of DVDP. You can create as many as you want, you can structure them in a tree and you can filter for them. I use tags to determine whether a DVD has a german audiotrack, what parts of the profile I have edited/locked, whether I have that particular soundtrack, ...
Tags can be set individually for each movie in the "Tags" window or in batch process under Collection->Flagged->Edit Tags.

2) Under "File" you'll find "Open Database". And there you can create a second (, third, fourth) database that's independent of your first one.

3) Some people use the collection number to create logical ranges. In my collection 1-10,000 are movies, 10,001-20,000 are TV show discs and 20,001-30,000 are Special Interest DVDs (stand-up comedy, documentations).

4) DVDP has a Box Set feature which is normally for things like the "Alien Quadrilogy" where you have a box set profile and then child profiles for each movie. Some people also use them to put a "bracket" around their DVDs, HD-DVDs and Blu-rays. You open the "Add DVD" dialog, go to "Add by Title", uncheck "Download from Invelos". Then you can create a so-called "manual profile". When you edit the profile there's a tab "Box Set Contents" where you can add all the profiles you want.

Here's what it looks like (I get so tired of tracking this photo down every month, I've finally added it to my signature.  ):

Cole, only 1 of your local databases can be uploaded, unfortunately. That's why one of the other 3 methods listed would be the most preferable. For myself, tags would be my choice if I really wanted to keep track separately, since you can do almost anything you can imagine with them.

Nice about your feedback. But if I choose to create second database, can I also upload it like my default profile? I mean so I can share it online?

Also you wouldn't have access to the profiles on your mobile device, same goes for the tags option.

Another possibility would be the "My Tabs" Plugin which can be totally customized. So you could create new tabs for BluRays, Music-DVDs, etc.
