I have written a process down here in this forum a long time ago. Involves a bit of messing around but get results.
The key - and I assume you are running everything as a WMA file is breifly as follows:-
1. Load up Windows Media Player (10 or 11 is probably idea)
2. Edit all the tags as you see fit. There are a number of fields which are usually redundant on the WMP which Beoplayer actually uses.
3. Rescan WMP for media, then close WMP and Beoplayer. Delete all the *.IDX and *.DAT files in the C:\Documents and Settings\User\Application Data\BeoMediaDatabase directory and those in the Backup directory.
4. Re-Scan with Beoplayer.
All should be how you wish it to be. There should be more detailed instructions in my earlier BS5 threads
