找到解決方法了

mplayer dvd:// -dvd-device VIDEO_TS/
                                            ↑
                                         放 VOB 的目錄

再用j 切換成繁中字幕，就OK了

用GUI 居然沒辦法自動讀出字幕，真是詭異.......

我用MPlayer播放DVD光碟時, 按下 j 鍵可切換字幕. 不過某些語系的字幕不會顯示出來, 原因還不明.
註: MPlayer 輸出的訊息可以看到有找到字幕;
註: 另, 某些語系字幕沒顯示出來時, 仍可用 j 鍵切到別的語系。
mplayer dvd:// -dvd-device k:

(k:是我的DVD-ROM)

Fedora Core 6，mplayer 是 MPlayer-1.0rc1，影片是這個

直接播放VOB 檔時，影像正常，但沒有字幕，且右鍵選單裡的DVD Subtitle language 是 none

也試過用 mplayer -ifo VTS_01_0.IFO VTS_01_1.VOB ，還是沒字幕 (字幕為開啟，切換語言無效)

也有試過把VIDEO_TS 及AUDIO_TS 再包成ISO 檔掛載，播放時一樣無字幕...

是不是需要裝額外的library 還是套件呢？


任何的建議或提示都非常感謝
