Currently I'm using an HDLink box to de-embed audio to a pair of analog studio speakers, as the Extreme uses digital audio outputs, and unlike the HDLink I didn't have an audio d-a on hand. This works quite well, however when I use the live downconvert function I have to also tell the card to reclock my 23.98 sequence to 29.97. Not a problem, except for when I'm using the HDLink pro, which for some reason doesn't like the 23.98-->29.97 signal, since all I get is a slow flashing indicator (every 1 sec. or so) on the back of the unit. Anyone seen this before?
