There's a new reel HD pci-e card available, see http://vdrportal.de/board/thread.php?threadid=80489&sid=ef2e2bfeb189c680... and http://www.reel-multimedia.com/de/shop_extension_hd.php
It's apparently an ATI vAti 2400 pro Mobility card, and in the thread at vdrportal.de it's stated that linux drivers will follow in October.
Does anyone know if this driver will support h.264 decoding in linux with this card?
