Philips GoGear: delete music from library & are there any Unicode
Here's the deal:
Open the Philips Device Manager that came with the install cd, and do a Repair - this will erase everything so you can start over from scratch. This will also take care of your squares issue.
No dice on the playlist issue - sorry.
Next, you have to disable the auto sync feature in Windows Media Player to prevent it from auto-loading all of those songs/files that you don't want. by opening Windows Media Player, highlighting the Sync tab, clicking on the little black arrow to bring down the drop-down menu, clicking on "Set Up Sync" (make sure your mp3 player is connected to computer, or this option will not appear), and unchecking the box that says "automatically sync files to my device". This will give you manual sync instead.
