When playing a DVD with a regular player, there are typically only
Left and Right audio channels. I understand that these outputs can be
fed from a DVD player to a surround-sound receiver that somehow
demultiplexes the audio signals into the respective speakers (front
right, front left, rear right, ...)

There are also surround sound receivers/amplifiers with a built-in DVD
player.

Would the surround sound receivers/amplifiers with built-in DVD player
more accurately re-create the sound into the 4+ speakers?

Or is a regular DVD player with Left/Right channels feeding the
surround sound receiver just as good?

Thanks,

Michael

No. Even the cheapest $25 DVD players have a coaxial and/or optical surround
sound output connection (for Dolby Digital or DTS surround sound).

You have to use the surround sound output connection, not the left/right
channel output.

No, just use a normal DVD player and a normal surround sound receiver.

No, not nearly as good.
