I solved my problem. And it might be the same one many of you are having. After not getting any suggestions on this board I went over to ISO News where they were more than helpful and gave me sever ideas on how to fix the problem with step by step instructions.
Strangely enough it was a very simple solution. The HP8100i drive in all of their firmware revisions, with the last being 1.0g, is not capable of burning the full 80 minutes. It peaks out around 78 minutes and some odd seconds. However, it never gives you a clue that it can't actully burn the full 80 minutes. This is why Disk Juggler appears to do the burn fine. There is sony drive that is actually the same as this one and a firmware patch was release for it, that when applied to the HP drive will allow it to burn up to around 79:57. I was directed to

to download it. It works, no problems!
