真巧 前兩天我也遇到類似的問題 我是因為要加上新的選單 保留原來的字幕 所以得將新 DVD 的字幕打開

用 IFOEdit

Load original VTS_xx_0.IFO
Load VTS_xx_0.IFO

1. VTSI_MAT
[0255] Number of Sub-picture streams in VISIT_VOBS : 1
[0256] Language English (或是你的 DVD 所用的語言)

2. VTS_PGCITI -> VTS_PGC_X
Copy PGC subtitle color from original VTS_xx_0.ifo and paste it into the new PGC of VTS_xx_0.ifo

[0008] Prohibited user operations : uncheck Menu call - Subpicture
[001c] Sub-picture stream 1 status : -2147483648 [80000000]
(這是第一個字幕 如果是第 3 個字幕 請改 stream 3)

3. Check root (VTS_xx_0.IFO)
SubPicture 1: Language English (或是你的 DVD 所用的語言)

Save VTS_xx_0.IFO

Load VIDEO_TS.IFO

1. VMG_VTS_ATRT
VTS_xx: Number of Sub-picture streams in Title (VISIT_VOBS) : 1

2. root (VIDEO_TS.IFO)
SubPicture 1: Language English (或是你的 DVD 所用的語言)


Save VIDEO_TS.IFO
