I have been reading about this device and it seems like it would be of more use to enhance standard-def DVDs, if a choice had to be made. I have a Pioneer Elite DV59-AVi DVD player which has an HDMI out, so I'm thinking that is where I would use it. Does the Darblet also pass audio, or not? I use a coax digital connection anyway with this player. Thanks and I would really like to have one of these!
