Your comment explains why /sdcard/Android/data/lms/mp.... would fail if I had indeed copied the files to /sdcard/sd/Android/data/lms/mp.... But my memory is that android.os.Environment.getExternalStorageDirectory() returns "/ sdcard" on BOTH the Moto droid and the Samsung Captivate. Unfortunately, I have limited access (time) to that phone since it is in use as a "in case of emergency call 123-4567" type situation. So I will have to wait to test this possible solution.
