Alan,
 
I'm afraid that nothing else comes immediately to mind.
 
Have you tried connecting your PTR2 to the computer with a USB cable and
tried playing the individual files on the CF card direct from the PC?  The
only reason I suggest this is as a possible way to track down whether the
copying process or the original backup process caused the files to become
unplayable on the PC.
 
I would have thought that .WAV files should normally play on a PC but I am
no expert in this area.
 
Jamie

Hi Alan,
 
I don't know if this would match your situation but I suspect that this
might be to do with the way that the PTR2 protects against illegal copying
of CDs..  What I'm about to say applies to CDRs that are master CDs e.g.
music CDs from a shop and not CDRs that you have recorded yourself.
 
I've copied a section of the PTR2 manual below which explains how the PTR2
works in this regard.  Essentially, you can make one legitimate copy of the
original CD but you cannot use a copy of a copy as that would infringe the
rules.
 
*****Text from manual begins:

2.3.2.  Digital sound rules.


 

The PLEXTALK PTR2 conforms to SCMS (Serial Copy Management System)
standards.  This standard regulates the recording and copying of digital
signals between digital audio devices, up to 1 generation from the original.

 

The main principle of the standard is that commercially sold digital music
software, such as CDs, MDs, analogue records, FM broadcasts and the like,
made into digital recordings, can be copied, but copies cannot be made of
those copies. 

 

During digital recording, PLEXTALK constantly verifies the SCMS status,
track by track.  Tracks for which digital recording and copying are
prohibited cannot be copied using PLEXTALK.

 


2.3.3.  Music CDs.


 

Copies of Music CDs are for individual enjoyment and, under the Copyright
Act, cannot be used otherwise, without the authorization of the copyright
holder.  Music CD-R or CD-RWs, which are special CDs for music format
recording,  contain special codes to identify that additional money has been
paid, as compensation for private recording, with the objective of
protecting music copyrights, in the same manner as devices such as MDs.




PLEXTALK is equipped with a mechanism that checks the identification code to
permit recording on Music CD-Rs alone.  Music CD-R or CD-RWs are sold by
several companies.  When purchasing them, it is necessary to check whether
it is an audio/music type CD-R or CD-RW or a data type CD-R or CD-RW.

 


2.3.4.  Types of copyright information used by PLEXTALK.


 

PLEXTALK can read the copyright status of files or tracks in CDs or CF
cards.  It recognizes 4 different copyright states.  These are "MASTER",
"COPY", "DAISY" and "No copyright information".

 

.        "MASTER" means that you can copy only one time.  Whenever you have
copied from the master, the copyright status of the copied file or track
changes from "MASTER" to "COPY", which is in accordance with the SCMS
standard.

.        "COPY" means that PLEXTALK will not allow you to copy a file or
track again, but you can move the file or track from CF card to CD.

.        "DAISY" is the PLEXTALK's original role, you will be able to back
up the DAISY title to the blank CD or CF card without limitation.

.        "No copyright information" means that it's your original contents
or there is No copyright information in the media.

 

NOTE:  On Music CDs, each track has its own copyright information,
therefore, in some circumstances, you may have media containing tracks with
a mixture of "MASTER" and "COPY" copyright information.

 
*****Text ends.
 
Hope this helps.
 
Jamie

ptr2 on other equipment


                        Hello there
 
hopefully someone on this list can give me an answer to my question.
 
a few days ago, I had to back up a large number of audio cds (cdr's), to my
ptr2 in order to use the resulting wav-files in another location on a pc at
a later stage.
 
the backup process itself whent absolutely smoothly, and I filled up my 8 GB
flash-card with about 10 CD's in pcm-44.1KHZ stereo.
 
when I got home to my pc, I transfered the content of the card to my pc.
Again, no problem, the files transfered just fine. I then want to pull out
the wav-files from the daisy-structure, as this is really not a daisy book,
but just tracks from gegular cds I'd like to yous as regular
wav-sound-files.
 
well, I can coppy the files to any location I desire, however I am unable to
play any of them on any of my pc-based players! none of them will open the
files, I just get a strange mesage saying that perhaps I need another codec
to play this content. I find this very strange, as this is just regular
wav-files, and I should be able to play them as regular files, also, right??
 
Does anyone on here have an idea what could be wrong and how I can saulve
the matter?
 
all the best from allan
