We're working on it right now. Not specifically Plex, but in the
compatibility issues of rip output in general. The latest beta
version 1.3.3f is a big step in that direction, and I'm still focused
on it. I believe Plex uses some of the same libraries as Handbrake,
which I use to test as well (libdvdnav and libdvdread). If you're not
already using the beta version, I strongly suggest giving it a try.
You can switch back to the production version just by downloading
it ... and no worries about registration information being lost.
Kind regards,
