Check out this page Virtual Machine Jumps and Calls to see when to use Jump and CallSS.

Basically, you use CallSS to call a menu from the movie, and later you can resume playback by RSM command or using Menu button on the remote.

Jump is used mostly.
CallSS is used as a post command in VTS PGCs where Jump is illeagal.
Why its been done that way I don't know but check out on :

When Jump command is used it just - jumps. Playback goes on from new place. Call command saves current playback position so that it is possible to return to this place using Resume command.

It doesn't appear to work like that in my experience.

If that were the case then why is the jump illeagal as the last post command of a PGC when resume wouldn't work anyway ? And Call is illeagal as a precommand in a PGC....
Your probably talking about buttons right ?

CallSS works quite well for me as a PGC Pre command in a Title domain. It's illegal in a Menu domain, whether it's Pre or Post commands.

Even if CallSS is the last Post command for a PGC, you still have to provide resume cell address in order to accommodate possible RSM (resume) command in a menu that's been called. RSM is pretty much equivalent to a user pushing Menu button on the remote while in the root menu, so resume point must be saved whether you're in the middle of the playback or at the very end of it.
