Peter,
Thanks for all your help, I now understand the dynamic database and how it's used. I have a few more questions... )

I'm planning on adding a few new "tags" and I'm wondering the best way to do this. I've added two new tags in a tune fid: "starttime" and "endtime". They are used to set where to begin and end playback of a tune on a time scale. An example: The song "St. Robinson and his Cadillac dream" by the Counting Crow's is 15 minutes long, and is composed of two songs separated by 8 minutes of silence. By setting the endtime, I can stop the playback at the end of the first segment. I have the feature working on my empeg server using libMAD for mp3 playback, but I am wondering how I allow the user to make changes to this tag on my 3rd party player?

Given that the /drive0 partition is mounted read only, like the empeg. I don't want to remount it RW just to make changes to the fid | 0x1 file. I could allocate another scratch partition, and write out the changes to the fid | 0x1 file, (like the dynamic database), and then update the real fid | 0x1 file when I rebuild the database. But how would you do it?

PS I'v attach a picture of my 3rd party touch screen player. Eventually, I will release it on sourceforge.net...
