It's seems to get it it to work, only prob is, an error message seems to pop up a lot, which can make watching a movie annoying.
I don't know what they did, but this new update seems to have really messed up the player.

The error messages that popped up seem to be about not being able to connect to the server, which is new.
I've had the player on without the internet before, and these errors never happened.
Edit: OK, so maybe the error messages won't come up once you actually start the movie.
You'll get 3 error messages once the player starts up, then a few more once you load the rifftrax.
After that you'll get a few more, but then the errors might go away, I haven't started watching a movie a whole lot yet, so I'm not 100% sure.
This way might be the best bet to getting the player to work, until they figure out whats wrong.
Oh, and after you load the rifftrax and the DVD starts, you can turn the internet back on, and it's fine.
