I tried using MovieFactory to burn a MPEG-2 clip on a DVD+RW with a Ricoh MP5125A DVD+RW recorder and play it on a Pioneer DVS737 Player. I have checked that the Pioneer player is compatible with DVD+RW, and updated the lastest firmware on the Ricoh recorder and latest patch on MovieFactory. The authoring on MF is very easy and the recorded DVD+RW played well with CinePlayer and PowerDVD. However, when I play it on the Pioneer DVS737, it doesn't have any sound. I have also checked that the audio rate was 48Khz during recording. The MPEG-2 file was a clip shot by Sony IP220 and converted into MPEG-2 using MovieShaker.The MPEG-2 file plays fine in all RealPlayer, MSMedia Player...etc. Please help.
