Either this was a coincidence or a hint, that this really was a borderline defective disc.
All the reports here are a little ... inconclusive.
I did resolve some of my other issues related to resource consumption. Those were related to start priority. I removed a few apps that appeared to cause conflicts and have no further resource consumption issues.
I tried CloneDVD. I can rip the entire DVD to one file but not individually, same error message. I will send a note to BB and tell them they have file corruption with their master.
