DVCam & miniDV uses uncompressed 16/48 PCM audio encoding. But
the NTSC video (480/720i) is lossy, similar to MPEG2 encoding.<br>

<p><font size="5">If I recall, mini-dv was a medium dedicated to
Sony's lossy coded format. If I'm right then the so-called "16
bit 48 kHz" files are lossy encoded. The lossy encoded
wordlength in the file is apparently 16 bit but when decoded
it will expand to 18 bits in linear pcm format (formerly lossy
coded) or more. <br>

<p><font size="5">And if I'm right then David Josephson's point
about finding the original player makes sense and you have to
play it from the original software. I suggest having a
bit-scope on the digital output to sense the output wordlength
coming from the decoder. You could do that by playing the dig
out (SPDIF) into a good DAW and run a plugin called "bitter"
on the bitstream. <br>

I'm in the process of dubbing music performance with world class players I recorded 20-25 years ago using a Canon XL1 writing to MiniDV. The audio is 16-bit 48 kHz, I recorded acoustic music with very good mics. The XL1 has pretty good glass, well above consumer grade.
I've successfully managed to write DVDs with FireWire between a semi-pro player and a decent consumer DVD recorder. Now that I have the DVDs, I'm looking for a method to make bit-for-bit copies of them. I have no rights management to deal with. I need 3-5 copies of each program. My goal is not add a generation of data compression, without the need to make a transfer from the master for for each copy.
I've found a review of a half-dozen or so Windows programs that seem to do it, but I don't trust the reviewer to know about data compression and generations.
Any advice? Places to look?
Thank, Jim Brown
