Trying to play Star Wars on old DVD player

I got a used rental Star Wars Revenge of the Sith DVD, it played normally
with sound track but no voices on my old DVD player.

Went to dept store, they advised combine audio outputs into monoural audio
input in the TV I use to see the DVD. Also, I bought the new DVD, first it
went into a loop playing the intro on the DVD, finally got the movie to
start, got sound track but the voices are silent with speech captions below
the screen.

What is going on?

Also, there must be several versions of the DVD, the rental DVD had no
intro section, and the movie played fine, just no voices.

I know a new DVD player and new audio system would solve this, but not in
my budget. Hope some advice can make the old system work with Lucas fancy
audio.

====================================
Go into the menu on "languages" or "set-up"
and set the audio to dolby stereo (NOT 5.1).

Check to make sure your DVD setup (usually accessed with no disk in
player or with disk in "hard" stop position) had audio set for
"Bitstream" and not "PCM." If it is "Bitstream" you could also try the
reverse, and put it into "PCM" mode.

Other than that, I'm not sure.
