Seems like I've been able to open BDMV files that are on a hard drive with Makemkv in the past. Now it opens it like a folder, then I open the Stream folder, then the m2ts files are grayed out. I threw out the preference file in the library. That didn't change anything. It opens physical Blu-ray disks fine.

You need to open index.bdmv under BDMV folder.

Thanks. I'll give that a try on the next one.
