Easiest way to do this is to go to the Media Settings page of my.pogoplug.com, then click on the settings link next to the name of your Pogoplug under the heading "Your Pogoplug creates previews of pictures, movies and music from the files on your hard drive to make sure that you can view and share them across all web browsers and mobile devices."

This will bring up the Media Processing Options dialog with three choices
Allow Pogoplug to optimize videos for playback:
Allow Pogoplug to process media meta-data:
Allow Pogoplug to generate thumbnails:

Set Allow Pogoplug to optimize videos for playback: to "Never", and the device will play your original video.

Hope that helps!

Really? So we have to do that each time the Pogo decides it's not gonna play nice? Really? REALLY? I still can't get the bloody thing to play more than 10 seconds even with files that were handbrakes Universal and play just fine on all my iPods. If I turn on sharing for the XBox, I can even serve 'em up there, but not on my iPod.

The thing you need to delete to clear them videos is a hidden folder called .cedata.
1) Go to Media Settings and click the settings link next to the name of your Pogoplug bringing up the Media Processing Options dialog, and set transcode to never.

2) Safely eject your drive, plug it into your CPU, and delete the .cedata folder

3) Plug your drive back into your Pogoplug. Your iPod friendly videos should play just fine assuming you have the bandwidth - hope that helps!
