On Windows XP, if you use ProTools 7.x, know that it only supports Quicktime 7. What is the link you will say, with the Parhelia card?
Well, this card is perfect if you have ProTools 6 and if you want to have branches in two steps and a DVI or VGA video on a return tl when you do the post production and of sync, but only if they have quicktime 6.3 and Pro Tools 6.x, and not over!
If you have ProTools 7, forget this card immediately.
Basically: for use ProTools, the Parhelia will run with QuickTime 6.3, which even runs only on ProTools 6. This card is deprecated.
I do not know if it works better with other configurations.
However, apart from Protools, the video signal coming out of Windows Media Player trs well on the TV monitor and can easily find the rglages to take office in two clicks or even three.
