Nope.  DVI doesn't have the lines for audio, which electrically, is the
only real difference between HDMI and DVI.

I saw that card in the advert, and after I went looking at the specs on
the BFG website, I decided against it (looking at the selection on
newegg now, same cards, same 'out the door price', no need to drive a
half hour to get it).  I'm glad I did now with what you have reported.

Keep in mind that from what I have been able to find online, the NVidia
cards can not bitstream DTS HD or Dolby True HD, but convert it to 7.1
LPCM, quite like the 'fat' PS3.  Somewhat frustrating as the current
batch of ATI cards can bitstream the HD audio.  Might be an issue for
you if you are watching anything with those audio codecs on your myth
