I recently purchased your DVD

Question

I recently purchased your DVD video player ( 3140 ), which I was told could playback A DVD-r which I had burned on with HighMAT technology on my HP Media Center PC...from my Microsoft Windows Movie Maker. Your DVD video player seemingly does not read this format. Please tell me what to do; I have so far invested hours and hours on my Movie Maker storyboard and now can't play a burned CD. ...Bob Schwarz [phone].
