This command links to a PTT (Part Of Title) in a specified title in the current VTS. A Part-Of-Title is uniquely identified by its program chain (PGC) and the program number (PGN) within that PGC. The DVD specifications support up to 255 PTTs per each PGC. PTT is commonly referred to as chapters.

The PGC issuing the command JumpVTS_PTT has to be in a title domain or title menu domain (either VTS or VTSM). JumpVTS_PTT is often used to link a VTS menu to a chapter in a title. In the title domain, this command is often used to jump from a title to a chapter in a different title. LinkPTT can perform the equivalent function of this command and is more efficient if branching to different chapters in the same title, since the same title number is implied. JumpVTS_PTT is not allowed in the First-Play domain and the Video Manager VMG domain.
