dvd刻錄的

我用dvd刻錄機刻錄影音文件文件時，總是提示我：'You are about to create a multisession write once DVD disc. Session no.2 and above will not be readable with some DVD-ROM drives and operating systems prior to Windows XP. How do you want to continue?'
三個選項：Quote:Burn Multisession Anyway；Burn Without Multisession；cancel.
我已經知道用第一項刻錄後續文件夾無法訪問，但是現在的問題是：我可不可以選第二項？還有，是否我應該采用什麽格式呢？ISO?UDF?UDF/ISO?
