I have an avi file saved to my hard drive and it plays fine on my windows 7 pc.  However, when I go to http://my.pogoplug.com/ and I select the file a paly button does appear, but nothing happens.  Initially I thought it was perhaps slowly converting the file or whatever it does in the popgplug environment, but I waited a full day and still no luck.  I even tried to share it to myself and still  it did not play in the popoplug environment.

I hope this is not an issue as one of the big selling point to me about pp was I thought I could easil play and share avi files without people or myself wondering why it was not playing.
