If you have a custom built kernel, or it is just old, you could be missing proper AGP support for your new board. I would first build a new kernel or use a recent one from Debian unstable. I also recommend changing to the AMD64 Debian port, because it will gain you additional 10-20% performance in most programs (think 4000+ against 3500+). Just make sure all the programs you use are available as 64-bit versions, so that you don't need to set up a 32-bit chroot environment, which can be a bit painful in Debian. X.org has the advantage of XvMC for NVidia drivers, and also better support in various video programs, which you might want to run in parallel with VDR and Xine. AFAIK recent versions of Xine work better on X.org than DirectFB, but I might be wrong here. I'm also not sure if the tvtime deinterlacing algorithms work with full framerate (50fps for PAL or 60fps for NTSC) in DirectFB either, so X.org may be better suited for advanced post-processing. -- Niko Mikkil?
