Bizarre problem with DTS soundtrack on Iron Maiden "Rock In Rio" DVD
 

Hi All,

I have a bizarre problem with the DTS soundtrack on the recent Iron
Maiden "Rock In Rio" DVD - just wondered if anyone else had had the
same problem, or had any advice.

I have a Pioneer DV-656A DVD player and a Yamaha DSP-A595a amplifier,
connected via an optical digital link. I also have the 6-channel
analogue outputs on the DVD player connected to the external decoder
inputs on the Yamaha. Finally, I have a Microsoft Xbox console
connected to the other optical digital input on the Yamaha.

This setup has worked flawlessly on every disc I have used in it so
far, on both DTS and Dolby Digital soundtracks. However, when using my
default setup - Pioneer DVD into Yamaha via optical in, the DTS
soundtrack on the "Rock In Rio" DVD has glitches - the sound
occasionally drops out to nothing for around 0.5 s at a time. This
happens at the same place on the disc each time - if anyone would like
an example, there is a glitch immediately after Bruce Dickinson says
"Janick Gers comes to Rio De Janeiro" at the start of the track "Two
Minutes To Midnight". This is only a sound glitch - the picture is
unaffected as far as I can see. Also, the amp still "sees" DTS during
the glitch - the DTS indicator on the display doesn't even flicker.

First thought was to clean the disc - no joy. I then got a replacement
disc - the same glitches in the same places. So, it isn't a problem
with one particular copy of the disc.

I then started fiddling. If I play the DTS soundtrack via the
Pioneer's internal DTS decoder into the external decoder inputs on the
Yamaha, there is no glitch - there is a faint crackle in the sound at
that point, but definitely no drop-out. Also, if I play the DTS
soundtrack from my Xbox into the other digital input on the Yamaha,
there is again no glitch.

So, I am now rather confused! If the sound is fine when played from
the Xbox into the Yamaha, then the DTS decoder in the amp must be
functioning correctly. If the sound is fine when played from the
Pioneer's internal decoder, then the transport in the Pioneer must be
extracting the bitstream correctly to pass it to the internal decoder,
and it would seem likely that the digital out on the Pioneer carries
exactly the same bitstream. So why do I get the glitches when using
the Pioneer with the Yamaha - on this disc only?

Any advice gratefully received - I presume there is something weird
going on with what is encoded on this disc - not quite adhering to the
DTS standard, or errors in the bitstream. I'd be interested to know if
anyone else has had problems, and if they found a solution.

Cheers,

Simon

The opening 20 secs of the track Iron Maiden make a great ringtone tho.

Not sure why the rock in rio DVD does this, but i returned my copy for the
same thing. Do you have the horrible slipcase version or the newer amaray
case?

I was also playing it on a pioneer 656, so it could be somthing to do with
that?!?

Hi

This sounds like the layer change on the DVD.

There is a brief interruption to playback on almost all DVD players when the
laser switches from one layer to another.

Different decoders are more or less affected by this and will often
momentarily lose sync.

The inbuilt decoder in your DVD player would appear to be more tolerant of
the interruption than the decoder in your amplifier.

The reason the XBOX does not exhibit the symptoms at all is that - hardware
wise - it is basically a PC. DVD playback is buffered in RAM before playing
out. There is, therefore, no interruption.

Some high end DVD players also feature a similar buffer.

Steve
