Video Freezing

Hi.  When streaming a movie to an Ipad, the video often freezes and then restarts.  Its seems to work well for the first video (although this anecdotal) but then gets worse.  I saw another post re cache filling up.  Is this what is happening?  Any other thoughts?  It pretty much defeats the purpose of the drive as it eventually makes a video file unwatchable.

A related question.  Is there any other way to interface with the WMD other than the SanDisk app when using an IPAD? 


what is the source of the videos and what bit rate are they in?
