I'm needing help with an issue that I'm having with my Xoom since 3.1. I've converted my blu-ray movies to mp4 to watch and they were playing just fine in 3.0.1. Since the upgrade, my movies will no longer play. I'm getting the message that this video cannot be played. I'm using DVD Fab 8 to convert the movies to .mp4 format. Anyone else have this issue and found a resolution to it yet?
