DVD Preview (Show DVD)
Since version 0.92 it is possible to start a DVD soft player (like WinDVD, Media Player Classic or PowerDVD) to test the final DVD before burning. The soft player has to be selected in the Def.Settings before this button may be used. If you like to check the DVD structure before burning, you should not enable Auto burn DVD...
The soft player is started with either the VIDEO_TS.IFO file (appropriate for WinDVD version 3.2 and 4.0) or with just the DVD\VIDEO_TS path (works for Media Player Classic). In case of doubt, simply try both options.
