Just check out newegg or somewhere like that for the card that meets your
specs. There are cards in the $30-$40 range that meet most people's needs. I
believe all of the Nvidia 8000 series and newer cards will support the VDPAU
hardware acceleration and are currently the most reccommended cards for
myth. I think your confusion about HDMI may be because of HDCP. HDCP is the
hardware encryption that may be used with HDMI for encrypted sources like
blue-ray drives. I don't think that is supported at all in linux. Since you
will just be playing unencrypted material from mythtv you won't have to
worry about HDCP at all.
