This command resumes the playback where it was left off. The playback is usually interrupted to display a root menu
or a title menu using the remote control. This command is allowed only in the Video Manager (VMG) domain to support
title menu operations, and the Video Title Set Menu (VTSM) domain to support VTS menu operations. This command cannot
be present in the First-Play domain or the Video Title Set Title (VTS) domain.
This command can be combined with the Compare GPRM operations
for conditional branching. When combining, this command is
executed only if the result of the comparison is true.
