Hey. I have a HPDVD200i that dies a couple of weeks ago. HP sent me a replacement and now when I try to burn a movie, the picture is all jerky when played in my set top box. I have used the same authoring process as I always have - DVD Decrypter, IFOedit and TMPGenc and Meastro.... Is there some system or OS setting that I might need to change or does this sounds like another bad drive?
