Full-featured Card
"Full-featured Card" Euphemism that describes the early Siemens, Hauppauge and Technotrend DVB-Cards with onboard MPEG2 Decoder. From a today's point of view they are just outdated and forcing people to blow their money for a hardware decoder they don't need (every recent PC with more than ~500MHz is able to decode MPEG2 Streams in software without any extra cost).
No modern card design repeated this approach, Microsoft even denies to support this type of cards in their BDA Driver Architecture.
For a long time unfortunately VDR forces it's users to install at least one of these expensive cards in your system, however it is highly recommended to install the software decoder plugin instead and let the "Full-featured Cards" die better sooner than later. You can spend your money a better way.
