Having just read the manual for that m\c it says :
* DVD-Video Format (Video mode) is a new format for recording on DVD-RW/-R discs that was approved
by the DVD Forum in 2000. Adoption of this format is
optional for manufactures of DVD playback devices
and there are DVD-Video players, DVD-ROM drives
and other DVD playback devices available that
cannot play back DVD-RW/-R discs recorded in the
DVD-Video Format.
