If you imagine the yaVDR distro being a human body, its heart would most likely be the VDR (core) software package. The VDR core is mainly maintained and extended by its inventor, Klaus Schmidinger. yaVDR 0.2 will use the currently latest VDR developer version 1.7.14 as its "heart". Although many users of VDR are very happy with 1.7.14, the current stable version of VDR is still version 1.6 which was released back in March 2008. Version 1.6 doesn't contain support for HDTV and DVB-S2 cards, that's why it doesn't make sense for us to use it within yaVDR.
