HTPCnews has posted the venerable HTPC community guru SpHeRe31459's updated 2006 PVR Card Guide with tons of great up to date info on different chipsets like the Conexant (popular with Hauppauge cards) and ATI Theater x50 Pro Designs, ViXS (used in Nvidia DualTV and VistaView's new PCIe Saber2020 card) , NEC, and WIS Designs.

"This guide is to give people the background information and pictures to understand what hardware MPEG2 encoding card they own or are thinking about owning. This guide started off with the need to explain to people which card was which. This is especially true for those considering buying from Internet auction sites. There have been many cases of vendors claiming to sell one card but in fact have a different card. This is to arm you the HTPC user with an understanding of what the differences are between the cards.

This is a rebuilt and revised edition for 2006 and made especially for the new HTPCnews content system. Enjoy! "
