My continued frustration with this problem lead me to an archived discussion https://discussions.apple.com/thread/2020977?start=0&tstart=0 This lead me to beleive I need to use the reset password to fully repair my permissions as contained there. Also while booted in the install disc, I performed a Repair Disc on the StartUp disc.
After all this, when I restarted, the DVD Player was able to play DVDmedia files completely.
So I quess I solved my own problem.
