Re: MD: Unlimited SCMS from SBLive!?
Yeah, but what if the soundcard has not been programmed to send the data correctly, it could just be sending NULLs to the unit, which it then defaults to UNLIMITED, this could explain why the track index marks are not sent either Keith - Senior Development Programmer < Putting propeller-headed beany cap away!

I don't think that is a valid status for the SCMS bits. They are recorded and can be turned on and off in varioous combinations, to allow unlimited copies, one copy, or no dopies.

If the recorder did it all, and the information were not there in the signal, how could the recorder tell when the signal was coming from a premastered MD, or an MD track recorded from an analog signal, and know to lay down an SCMS-final recording, or when the signal was coming from an MD track recorded from a digital source and know not to copy?

RE: MD: Unlimited SCMS from SBLive!?
Larry, I believe you are correct, because this problem just bit me in the butt. I made original recordings to MD with microphones, and when I try to transfer them to the computer using a Hoontech soundcard with Yamaha drivers (which implement SCMS) it will not copy. Interestingly enough, if I try to copy a commercial MD I bought, it works fine, so it apparently is not marked as SCMS final. The original driver for the Hoontech card did not have SCMS, but I was having problems and updated it. The new driver will not copy original analog material that I recorded. Guess I have to go back to the old drivers and live with the (minor) problem.

OK, I think I understand better now. a) If I make an analogue recording to my hard disk it has no SCMS bits set, or is classed as 'unlimited digital copy'. b) If I make the same analogue recording to my MD the SCMS bit is set to 'digital copy once'. What surprised me was that the 'unlimited digital copy' from a) was preserved when subsequently copying between MDs. The SBLive seems to be "SCMS-compliant" and does apply SCMS to recordings, if I make a digital recording from CD to hard disk I can copy the resulting wav file to MD but subsequently copying from that MD gives 'NO COPY', so it is acting in the same way as the MD. It differs from the MD in that it establishes 'unlimited digital copy' for analogue recordings. In my view the SBLive! is doing it correctly and the MD is not. Why shouldn't someone be allowed to make multiple digital copies of their own analogue sourced material? I have to confess to some naivety here, I hadn't appreciated the generational loss digital to digital MD copy. In my head I imagined that the MD knew it was another MD sending data and just copied the data, then I thought about it some more. Doh! What's missing of course is a genuine MD to MD copy, faster than realtime with track and/or disk name data sent.

Re: MD: Unlimited SCMS from SBLive!?
Hi. If I remember correctly it is the MD recorder that adds the SCMS. If that is correct, then either you have a one of a kind recorder or the copy is not true digital. That's about all I can think of. I still don't see the point in wanting to make a digital copy of an MD that was, say, digitally copied from a CD. Don't forget every time that you make a copy it goes through a compression/expansion cycle. You can make an exact clone of a CD using a CD burner. That's because there is no compression. If the discs are of high enough quality and you are using a high quality CD writer, you should be able to make and copy of a copy of a copy, and so on. Each having the same quality as the original. Because of ATRAC this can never be the case with MDs. That's one reason that an MD recorder is not the best source to use if you are recording live music and plan on making many copies from the original. LAS John Graham wrote: > Here's a weird one.
