In the spring of 2005, Micronas Semiconductors announced the APB 7202A nGene dual-channel PCI-Express multimedia controller with support for two DTV transport streams and analog video. The analog component is handled by a separate chip, as the nGene chip does not support analog decoding.
There is currently no open source Linux driver for this controller chip.
However, Terratec has distributed a binary driver for their Cinergy 2400i card, which reportedly uses the Micronas nGene chip, at http://files-upload.com/308575/Cinergy2400iDT_Linux.zip.html. The code is dated April 2006; please post a report if you have tried it.

This card, from Prolink Microsystems in Taiwan, was demonstrated already at CeBit 2005 as the first PCI Express dual channel multimedia controller; cf. press release. It uses the nGene controller.
They claimed at the time that their PV-A425E model would be available "soon", but two years later there is still no trace of it.
