I purchased two of the 416-DVR 1-8 Channnel PCI PC DVR card w/software and the software I received was The DigiNet Center 4.13 -- NOT compatible with XP sp3 or higher. I found that Kodicom has released DigiNet 5.2 which is supposedly Vista Compatible. But when I downloaded the software it requires an Activation Key. Is there any License info available for the 4.13 that would allow me to Upgrade for free, or am I going to have to purchase two Activation keys at $100 a pop??
