Hi

I am willing to write a driver for some DVD card that have an MPEG-2
decoder on it.

The question is - what card ?

I understand that some DVD cards have drivers but only for reading the
files.
I also want the card to be -

1 - popular
2 - have a TV-out port.

Any suggestions ?

--ury

	I nominate the following:

	Sigma Designs REALmagic Hollywood+ Playback Card.

		http://www.sigmadesigns.com/product_hw+.htm

	This is the card that comes with the Toshiba DVD-Roms.  Pawing around
the STB site, it appears that they are pushing this card and the primary
chips it uses as an OEM to DVD vendors, so we could see it pop up bundled
with other drives as well.

	From looking at the chips, it appears to have the decoding on
the board.

	VLSI Chips on board:

	Sigma Designs	EM8300		MPEG-2/DVD Decoder
	Sigma Designs	EM9010		Video overlay controller
	Unknown Manf	V53C832HQ35 (2)
	Analog Devices	ADV7175AKS
	
	Inputs:		VGA-IN
			CD-IN	(On board)
	Outputs:	VGA-OUT
			TV-OUT	(S-Video)
			Digital Out (RCA Jack)
			Line Out (Sterio mini-phono)
			Line Out (On board)

	The Sigma Designs EM8300 and EM9010 chips are available as OEM
components, so it should be possible to get developer manuals, technical
specs, and guides from Sigma Designs.

	Sigma Designs is at:

	Info on the EM8300 is at:

Several people including myself have already tried to get specs and 
development information for this card and the chipsets it uses.  No 
luck.  Look at the archives on the LinuxDVD mailing list for more 
information (linuxdvd.corepower.com).  If you can get a CSS 
license they will release information, probably.  The problem with 
this card is that audio decoding happens in software (as well as a 
CSS decryption).  The Creative Labs DXR3 is also based on the 
chipsets used in the Hollywood+.  They also are very hesitant to 
release information to unpaying customers due to lack of support 
personel, specifically with regard to the linux platform.  

They are working on a new card and chipset however that they do 
plan to support fully under the linux OS.  They have no solid 
release date for the new card or the linux drivers for it, but 
estimates put it in the December and January timeframe.  It is 
suggested that those interested in this (DVD decoding support 
under linux) subscribe to the LinuxDVD mailing list to keep abreast 
of efforts in that area, and to contribute.

March 7, 2003 - The SCO Group filed legal action against IBM in the State
