FCP 5.1.4 -> Sure is Buggy!

Ok got a new MacPro with a fresh (legit) copy of FCP. I though with a new machine I would be past the stupid quirky FCP buggyness!

Waveforms are non existent on the timeline and in the viewer:

-When a sequences prefs are set to "show audio waveforms" all I get is "x's" in the timeline
-When an audio clip is viewed in the viewer all I get is funky black backgrnd with lines, or I can "see through" the viewer window, or the viewer window is blank, etc etc etc I dont see any waveforms

Final Cut Projects brought between an Intel and Power PC machine (both running FCP 5.1.4):

-Fonts automatically change to "#Gungseo"
-Clips on the timeline will mysteriously have a flash frame of an entirely different clip (this can be remedied when the clip is deleted and then thrown back on the timeline, but WTF?)
-When a sequence is played the video in the canvas goes haywire (different images of video flash like crazy throughout) but the sequence's audio plays normally.


Before you respond:
-Yes I've trashed prefs, restarted computer/program
-This happens on multiple machine both PowerPC and Intel not just one.

Thanks!
