Have you actually tried to play the whole song through in Juke Box or are you just playing a few bars of each? I noticed in re-reading your post that you had a few check-boxes selected for Juke Box options. Maybe deselecting one at a time and trying again would be helpful. Also saw that you are running build 304. If you have maybe old builds like 301 or 303 you could install them and see if it is build 304 adding some issues.
Good luck.
PS - also noticed that Mac hadn't advised trying the Return to Factory settings option (I couldn't believe it - that is often his first suggestion and a darn good one at that). Might be something to try as well.
