jendand: Not sure on the buffer. I looked a bit for it. I just found a value that worked out of the box and set that as default and detail how and why to change it. Its odd, you can copy the same mp3 to the storage memory and it won't skip so I think it also has to do with the IO to the storage card. I personly use media player as I like the library aspect as well as control of it with Voice command. I can have the unit paired to my headphones, screen locked and the display off and still call up WMP and the album artist, etc as well as skip fw etc without having to unlock it.
If I do find a buffer setting yo will see it in an sp or later release. If you find one, let me know.
