This evening I upgraded to 2.1.9 from 2.1.8. After that my MP4 movies no longer play on my WD TV Live. I then rebooted my computer, but that didn't fix the problem. Then I uninstalled 2.1.9, deleted any Conceiva folders and profiles, and then reinstalled/reregistered 2.1.9. I changed my network connection speed for the WD TV Live profile in Meezmo to match what I had before, but MP4's still do not play. I can navigate my collection of movies and view the movie thumbnails/artwork, but if I try to play a movie all I get is a black screen. The time bar does not move.

Thanks,
John
