My DVD player and my digital reciever have both coaxial and optical
jacks.
Which connection should I use to get better sound quality or are they
all
equal?

Its all digital right? Unless there is a design flaw, I would think all
the
digital 1s and 0s would arrive in the same order either way. I don't
know
the protocol in these, but on a computer network, the protocol checks to
be
sure the data arrives exactly as it was sent for if a single bit got
changed, the data or program could be trashed.

Network transmissions allow for re-send of packets, audio does not.

I think spdif has a parity bit - but that's your lot !

Yes SP/DIF supports parity, but if the parity is wrong, there are few
alternatives but to mute or conceal the erroneous data.

Matt is correct as far as SP/DIf goes - if an error is detected the only
alternative would be to try to conceal the error as is done with CDs, since
SP/DIF and AES-3 have no protocol and lack a bi-directional connection for
retries.

One major difference between ripping a CD on a computer, and playing it on a
CD player, is that most ripping software supports retries.

When digital audio data is encapsulated in other protocols, such as the
protocols between a computer and its disk drives, then the protocol
encapsulating the transfer can and often does support retries.
