MPEG Hardware Decoding
Uses the IBM MPEGCD1M with 2MB SDRAM running at 100MHz
There is already a driver in the kernel tree that uses this chipset (stradis), so some of the work may already be done.
This component is not supported under Linux
Video In
Uses a SAA7111A chip, for which Linux has a driver. But last I tried this (a few years ago) it did not work.
Video Out
Uses a SAA7111A chip, for which Linux has a driver. But last I tried this (a few years ago) it did not work.
But User:Lentinj reports:
Probably not going to extend further than the TV out, which is controllable via BIOS. No projects as far as I know exist to support this card under Linux.
Dolby Digital AC-3
Uses the CSA8404A chip
Supports AC-3 Audio pass-through to an external AC3 decoder/amplifier
Linux has no support for this chip
