Hi John,
Thank you for your reply. Yes, we have already searched these forums, and the problem is, most of the issues people are reporting have nothing to do with Encore (instead being focused on Premiere, for example). We have tried some of the solutions proposed anyway, and they have so far not worked. My hope was that by posting specifically in the Encore section, someone might have some more relevant insights.
Yes, I am also aware that Adobe won't be supporting Encore in the future. Awesome. It would be really great if they offered another way to do blu ray video that worked for me, since they are no longer supporting the program that has in the past.
