"You format and record the DVD-R or DVD-RW on a Windows Vista-based computer by using the Live File System disc format. The Live File System disc format is incompatible with some consumer electronics DVD players and DVD recorders. Some consumer electronics DVD players and DVD recorders may require a Mastered disc format."
"To work around this issue, use the following guidelines when you use DVD-Rs and DVD-RWs interchangeably between a Windows Vista-based computer and a consumer electronics DVD player or DVD recorder:
• Use the Mastered disc format when you format a DVD in a Windows Vista-based computer.
• Finalize the DVD in Windows Vista before you try to play the DVD in a consumer electronics DVD player or DVD recorder.
• Finalize the DVD in the consumer electronics DVD recorder before you try to play the DVD in a Windows Vista-based computer."
