Hi, I have downloaded (and paid for) many albums and tracks from MSN. I now wish to transfer these so I may listen to them on my hifi. I'm not too keen on copied cd's so I would like to record them onto DAT. The problem is that there is some form of copy protection sent out of the digital coaxial socket of my Sony 77ES. I could transfer by analogue but the only output socket on my sound card is for headphones so isn't really suitable. Anyone know of a way of bypassing/disabling the DCPS? Any info gratefiully received!!

jitter filters
It has been reported that the Audio Alchemy jitter filters ("DTI" for digitial transmission interface) remove the copy protection bits from the digital stream as they buffer and reclock the data in order to make digital transmission more stable.
These cost abour $70 used, and, since they existed long before the DMCA, are possibly legal to for use to convey your own data from one digitial device to another.
You can do a search but here is a Link.

If for some reason you just happened to require your SPDIF data to be in Pro Mode, you could add a SPDIF transmitter to your Cd player for a few £ and run it in pro mode.

Pretty sure we have fair use in the UK that allows copying of videos for time shifting and Cd for use in-car etc.
Time-shifting is allowed, but the recording is supposed to be erased as soon as it's been watched. Apart from the specialised educational exemptions, that's all though. Copying carries a penalty of an unlimited fine and up to two years in jail
There are rumours that the law will change soon, but it hasn't happened yet!
My girlfriend tried to copy a cd to MD via digital cable, but
it failed because that particular CD had the COPY CONTROL logo
on it, and have information on it that makes the cdplayer set
a certain bit in the SPDIF stream that makes stupid devices
like her MD refuse to record.
My Sony PCM-R300 DAT hovever, allows to record protected stuff.
But the downside is, it also stores the protection information on tape as well, so it sets the same bits on its spdif output on playback.
But lets face it, the scms copy protection is a BIG joke.it is easy bypassed.connect the cd or dat digitally to a computer soundcard,
and record with cooledit or similar.It works.even with cds with
messed up error correction.
or you can buy a cheap device to connect between your spdif
cable that removes the copy protection.
or build it yourself.elektor magazine has had countless projects
doing this, mainly to let you make as many personal copies of
your own material as you want.even analogue recordings on DAT
is limited to only 1 or 2 digital copies
an easy approach is, get an CS8412 and an CS8404 and connect them together.read the datasheets for both, and you will
quickly understand how to put together such device.

Hi, Thanks for the info. I downloaded CoolEdit bit I'm afraid I didn't have much luck converting an mp3 without the copy protection signal. Every time I tried to play back the track, the dreaded 'copy prohibit' appeared in the diaplay of my PCM-2700. I will certainly look into the elektor project though.
