dvd player messed up sound when playing through optical.

Hi again. I recently purchased the samsung hd upconverter and have
found a flaw in it. I returned the first one and got a new one and it
is still happening. My problem is that when i play a digital source
through the optical cord the sound gos through real quick pauses every
about five minutes or so. I know that it is not the receiver or
optical cord because i switched them and still same problem. My
question is, has anyone heard of this problem, and what can i do to
fix it if anything? Also would it be fine if i used a coax cord
instead of optical, (im thinking that may fix it) would i truly notice
a difference. I love the dvd player i just cant take this fault,
please help. Thanks

Probably an unstable clock in your player.
Try the coax connection, this helps sometimes.

thanks is coax noticeably worse than optical?

In your case it's probably better.
It is said that coaxial has several advantages over ordinary TOSLINK
connections, a greater bandwidth being one of them.
The TOSLINK has the advantage of electrical (galvanical) separation
between components.
Then again, I've heard the AT&T glass connection should be even
better. This doesn't apply to your gear though, as they don't have any
of those.

I wouldn't make a problem out of it, just use whatever works.

If there's a difference, its usually worse. In this case, its worth a try.
Just use a 3' RCA-RCA interconnect to see if it is any better.

Only if it actually works better. I've got my doubts, but it's worth a try.

It is said that coaxial has several advantages over ordinary TOSLINK
connections, a greater bandwidth being one of them.

Problem is, coax outputs are generally driver through a special lossy
transformer that rolls response off above about 12 MHz to reduce EMI.

Agreed. And since light is a far less serious threat to the nice picture on
your TV set, opitical connections need not be bandwidth limited.

Agreed.

IIRC, TOSLINK has barely 7 MHz of bandwidth.
Have to look that one up, though. May be old information.

I've heard many times that the bandwidth is barely adequate but I just did
a quick Google and found
this.http://www.semicon.toshiba.co.jp/eng.../its2003_e.pdf

Seems like these devices have ample bandwidth. Don't know what was in use a
while back though.

It all depends on the current drive capabilties of the driver transsister
for the transmitter. There are now a number of transmitter parts. The design
of its driver is up to the equipment designer.

For parts like this - TOTX 111- yes - Toshiba quote 6 MHz in fact
