In March 2005, Philips Semiconductors announced "the industry's first integrated PCI Express dual global video and stereo decoder for digital home PC desktops and notebooks" (press release). The new analog decoder chip, the saa7162, uses the increased bandwidth of the PCI Express bus to capture to two simultaneous analog channels of live tv or baseband video (cf. product flyer) or up to four independent simultaneous digital TV streams (cf. Philips/NXP SAA7162 product brief).
In Oct 2006, NXP created a saa7162 product page that includes, amongst other information, an 18 page "preliminary short data sheet" for download: SAA7162 Product Description.
The PCI-SIG lists SAA7162 (dual A/V decoder) and SAA7160/SAA7161 (multimedia A/V bridge) as PCIe devices. According to PCIe specs there are two types of PCIe devices; Type 1, which categorize normal PCIe bridge devices, and Type 0, which categorize devices which have a specific/customized programmable interface. Unfortunately, the PCIe spec is not very detailed when it comes to Type 0 devices, and it is indeed this category that the SAA7160/1/2 reside.
Philips announced already in their reference design that they had written a Linux driver. In May 2007, they finally sent the code to Richard Dale and Manu Abraham, who are now writing a GPL'd driver under NDA. See the full discussion on linux-dvb.
This means there's still no released Linux driver for the saa7162, but support for PCIe cards incorporating the sa7162 chip is on the way.

(Someone needs to tell them it's hybrid, not hybird!)
ViXS Diamond Reference Design
In August 2005, ViXS Systems announced the Diamond PCI Express TV tuner reference design. The design provides for analog and hybrid (analog/digital) video processing, combining ViXS' XCode II-L Dual MPEG Encoder with Philips' SAA7162 Dual Video Decoder and Philips' TV tuner (press release).
