CD/DVD record

CD/DVD record

[Richard B. Johnson]

Hello all...
Recording this stuff is basically sending some commands to
a device and then keeping a FIFO full until done.

If `cdrecord` doesn't do it, one can hack together something
that works in a day or so,... really good stuff in a week.
Maybe it's time to ......  anyway ..... the device characteristics
should be kept in an ASCII text file so the software doesn't have
to be re-written everytime a new CD recorder becomes available.

Maybe the `cdrecord` author needs some competition. This sounds
like a good beginner's project....

Cheers,

Jörg may not be the best user interface on the planet but there is a
fair bit of complexity to CD burning.

Good morning, Alan!  Gotta have legs long enough to reach, though.

Lots of things that are easy to sum up on one sentence turn out the be 
hairy as a wookie, but yes, it does seem like a Simple(tm) problem.

Hmm...not sure about that. Not if you do want device specific fixes in 
there too...

Sounds good.

I'll admit to having some time on my hands but acquiring equipment to 
test with would be a stumbling block for me.

It would be nice if everyone could just put their egos aside and provide 
a united front wrt FOSS cd/dvd recording.

I was going to make some suggestions about how to do the above but then 
I have also been following the cdrecord thread and I'm not sure wading 
in on that makes sense...

Yes. There are hardware bugs (I once though bug was a reserved-
for-software word), moths are hardware problems ... Anyway...
some thought to putting all the differences in some writable
ASCII text and writing a program around that might be more
useful than complaining about an author's insistance upon
using some "strange at least for Unix" device naming scheme.

Just leaves me dispirited when people's energy goes to waste over issues 
like this though.

There's more important things to fix/build/hack.

The question then becomes - how many percent of devices in use need 
fixes to work?
A simple program with _no_ fixes, that works with correct devices only 
might not be that hard.
After it becomes popular people simply take care to buy working 
burners.  The old broken
tend to get upgraded after a while, or they can be used with the old 
cdrecord.

Take one thing at a time.  If you want to try this, start writing a 
program that works well
with your particular burner.  Chances are it'll work with many others 
too.  And then you
get patches from people who have other equipment.  You won't need to 
have everything
yourself.

Good point. Agreed.

Another good point. Agreed.

I hate to say it, but why reinvent the wheel? I'm sure that if Jorg 
doesn't support new technology there will be a project, either on 
sourceforge or freestanding, to create OpenCDburn or some such. It would 
be very hard to find someone as technically good as Jorg in this area, 
and hard to find anyone worse at working with others.

That's really sad, because if he would accept more from others and not 
insist on having the last (or only) word on every issue the software 
would move faster and with less hostility.

Actually this is only FUD spread by Joerg. He is definitely not the only man on
this planet knowing how to program CD/DVD burning equipment.

Generally cdrecord has one big deficiency, which obviously was intended:
it does not allow medium skilled programmers from drive _vendors_ to add
support for their latest hardware easily. Everyone has to beg Joerg, which
obviously increased his ego dramatically over the years.
It would be a lot better to start off a new project where vendors (or anybody
with skill and will) can contribute more easily, i.e. something that is truely
_open_.

Stephan

... and you can start standing on the shoulders of cdrecord, looking
at all the "strange stuff" and "vendor information" that Mr. Schilling
has used. After all, this is what the GPL and open source is all
about.

Rip out, what is useful, discard the rest, ignore the
complaints. That's how it works.

Good, glad you have a supply of SCSI gurus who want to dedicate all their
spare time to maintaining OS software. Joerg has been at this for years,
and I think that while identifying technically competent people is
possible, I doubt there's a big overlap with the set of people who have
nothing better to do with their spare time. When I said "find" I certainly
meant both qualifications.

A nice idea, but in truth if a vendor wants support in cdrecord a tech ref
and sample unit will almost certainly do it. I'd love to have support for
HD_BURN in Linux, but Joerg can't seem to get the info needed. I doubt
that people who won't release the info will trouble to write the driver.

Well, please read the docs for cdrecord again carefully. The story is not about
_free_, it is about _money_. Certain versions of cdrecord are licensed to
commercial customers for _money_. So please rethink your position.

Well, if I were owner of docs that are important for Joerg to make money and
had listened to him for the past 4 or 5 years and how he treated people (and
still does) it would be highly probable that I wouldn't be very cooperative,
too.
Please see the whole picture, not only what Joerg talks about.
Just take a clear look at his latest code changes and tell me if they look like
being done by an open-minded and friendly person to you.

Speaking from a potential commercial customers' point of view I decided against
using this software, not because of the money, but because of the
closed-everything-and-his-ears habit of the author. I don't see how this
project can survive its current author. Therefore I consider it an already dead
horse.

You mean ProDVD? It's a JOKE! I tried to buy a copy when it came out, 
and he doesn't take Paypal, and he doesn't take credit cards, and he 
doesn't want personal checks, and given the new rules about sending cash 
to a foreign national from the US I doubt if he makes enough to buy 
beer. Particularly since he found it easier to give a free license for 
personal use than to setup the accounts he could use to get money in 
convenient ways.

That is a problem, but I will pass on starting over when there is a fine 
  software to use. He's not the only dificult author around, or even the 
most dificult, just the most visible.
