do you mean this card from Asus ?
ASUS Xonar HDAV1.3 ? The Essential Home Theater PC Card

> Right now, we have already define the following features.
> These features will be helpful to decode and encode MPEGI MPEGII MPEGIV
> H.264, H.263+ , VC1, RM9.
> 1. Transform/inverse Transform
> 2. VLD/VLC
> 3. Q/IQ
> 4. Compensation : Intra-Pred / Motion Compensation
> 5. Estimation
> 6. Deblocking Filter
> 7. CABAC
> 8. Bitstream processing : such as start code finding
> 9. Deinterlacing
