Not for VDR.

No.

Currently, the only card supported by the VDR project is the
family of Siemens DVB cards.
What VDR does, to record a TV broadcast is, take the bits as 
they come from the sky and store them on disk. The MPEG-encoding
(compression) takes place at the broadcast side, not in your PC.
The family of Siemens DVB cards does not do MPEG compression nor 
does VDR.

The "ATI All-In-Wonder" cards on the other hand, receive analog
signals (that were not compressed at the broadcast side) and do 
the compression with a combination of ATI hardware and software
in your PC. VDR does not currently support this mechanism with
any card. If VDR should ever support this path, I would guess
that it would use an encooder card that is well-supported under
Linux. Maybe the KFIR card.
