I'm interested in a linux driver for these kits.

The Creative Labs DVD kit uses a card which is virtual identical to a
Auravision Universal Reference design, for which complete specification
is available.

Any information about work already done in this area is very welcome.

I've started an attempt to work on one, but info is difficult to get
on the Ziva DS CODEC chip (which Alan had tried to do for video4linux
sometime back without success, but is very busy now with other
things).  So far I've been having to do a little reverse-engineering
under Windows by maninipulating registers while playing a DVD.  The
first goal is to play unencrypted non-MPEG data from a hard disk file,
then try to get the codec working, then CSS authentication, then to
play DVD Video and then DVD navigation.  It really needs help, since
my time is limited (I'd setup a CVS repo or something, but I don't
have any server space).

I have the data books I could find on the chips (Vxp524, AnP82, Bt865,
etc) except for the Ziva DS MPEG-2 decoder, the Toshiba chip and one
or two more I think, though I wasn't aware of the Universal DVD URL
you give below (will check it out).  I've got a driver structure
loading, and some basic testing ioctls, though much time recently has
been spent working under Windows to figure out what is going on with
this card:

Apr 17 17:16:58 ztransform kernel: 
Creative Labs Encore Dxr2 DVD Decoder Driver Version 0.1
Apr 17 17:16:58 ztransform kernel: 
i2c: bus registered: encore
Apr 17 17:16:58 ztransform kernel: 
encore: Auravision VxP524 at I/O 0xe3000000-0xe30fffff, 
remapped to 0xc487d000-0xc497cfff, IRQ 11

So far, I've got the structure down and am working on controlling the
VxP524 to setup the VGA overlay and keys--though being at the end of
the semester for the next two weeks I am quite busy.  I do think that
DVDs will become quite popular in the coming years though.

PS Gerd Knorr's I2C module (+ i2c.h) seems generic enough I would
think to be a separate config option it would seem.

Are they just being stubborn, or are the asking for a NDA?  We are a
partner of c-cube - I can try asking them for the docs.  If they
require an NDA I can't help you though.

Its on my list to change this so that its an option to install anyway
and automatically gets created if needed by other things. If any folks
hacking parallel i2c stuff are listening I'd very much like a parallel port
i2c driver back end and maybe an i2c<->user direct interface adding as
i2c modules to 2.1.9x

It also depends on the kind of NDA. If we can reassure them we want to
know how to drive the external (PC) API for the device not take apart and
ship source to their loaded DSP firmware then perhaps we can get somewhere.
The biggest problem I've had so far is finding anyone in CCube who will
even talk. Its not so much as 'you dont exist go away' as 'we dont exist go 
away'

I know who to talk to.  Tell me what you want, and I'll give it a try.

I am very biased in this (I sell hollywood decoders on the side), but
wouldn't it be better to write drivers for decoders that are less buggy
than the creative labs ones?  I hear really horrible things about the
Creative Labs ones.  I believe any of our other competitors are more
reliable than Creative Labs.  Please correct me if I am unfairly
slamming Creative Labs.

I've never seen a problem with the DVXR2 cards.. Just the darn drives.. 2
so far that have just stopped reading DVD discs and 2 others that stoped
rading CDRs..

Does it include Linux drivers and/or documentation  8)

I may be mistaken in thinking it is the decoders not the drives.  Please
let me know if I am, I may need to reverse some advice to customers and
suggest that they buy new drives not new decoders if you are correct. 
Since I have not actually bought one myself, I only know these things
indirectly.

I have been getting reports that these kits tend to crash systems, not
get along with a lot (maybe most) motherboards, that Creative Labs
recalled the first batch of them, etc., and I would like to know more
from those who may understand the real situation with them.

We just switched to the STB Theatre card, which is too new to have Linux
drivers.  But if any of you writing Linux drivers would like to see us
bundle and support those drivers for Linux, and you happen to be writing
for a card we ship in our kits, I would be interested in doing so, and
if you can, send me an email letting me know you are writing such
drivers.

	At least with the IDE DVD drive that I have, plugging it
directly into an IDE port and using the regular Linux ide-cd driver
works just fine for reading both CD and the copy protected sections of
the DVD's.

	There is a protocol that the hardware decoder boards use to
tell the DVD drive that they are a licensed implementation and should
be allowed to read the copy protected sectors as well.  I have been
told that this protocol can be done entirely in software with a
standard IDE port.  Hopefully, somebody will reverse engineer this and
make it a demand loaded kernel module.  (Seriously, there is a lot
that you are allowed to do with copyrighted material that this sort of
hardware restriction prevents, and there are other important political
issues involved relating to your rights to do as you please with the
computer equipment that you bought and paid for.)

	I meant the sections that are *not* copy protected.
