Hey Simon,
i called your office thursday and spoke to your assistant.
In order to output HDV you’ll need to have some sort of Card which can display
HD like an entry level Decklink.
Your current system will output Standard def throught the hd link upsampled by 2 and that’s what we did test
at the office.
As i mentionned if you need HD playback at HD rez (1080) then you’ll need an HD card.
Hope this make it clear
Regards
