Re: [linux-minidisc] About PC to MD

[Taliesin Bardolobo <bardolobo@gmail.com>]

Well, when I said "fake sp in Sonicstage" I was meaning to that
trouble: If you use Sonicstage you never get same quality than when
you record using a digital output (a DVD player, for instance). So
yes, I was meaning pc sending a song that first convert to LP and then
transcode to PCM, then MD again encodes it to SP, and was hoping your
software could send PCM to MD without that intermediate conversion in
order to get a "good SP" (that is encoded by the MD machine, of
course). My fault for not explaining me well. So many years talking
about this problem in forums that I have get bad habits calling it
"fake sp"  :)

And you says your software do that, so...CHEERS!!! :)
That drives me to another question: is this available in present
version of QHiMD transfer, so I can just download it and use it this
way? (note: I have lots of blank media waiting to do this :p ).

And I know you can't record on sp in a HI-MD disk. I was meaning to
record sp tracks into a "normal disk" (not a iMD one) on a Hi-MD
machine with NetMD mode. For example, you can tweak RH10 into service
mode to enable sp recording (although you lost some other options by
doing this) and I can recall there were other models you can do the
same with.
My question was about if there will be any trouble recording SP with
such machines, since I know they're are some actions restricted by
hardware to some units (RH1, for example, can do things other HiMD
units can't). I supposed as far as your machine can record sp, you can
use your software to do so, since sp encoding is doing by the unit,
but maybe there is any problem I ain't conscious of (although I hope
no :D )

Thanks.
