Hi, The userspace drivers are different from v4l-dvb-experimental - they make use of the existing drivers that came with your kernel so you need to compile the appropriate in-kernel drivers. I'm not sure exactly what you need, but you'll need at least Video for Linux, plus both the V4L1 options and "DVB for Linux". You probably also need some other (hardware-dependant) drivers, which the kernel config tools won't let you choose unless you deselect "Autoselect pertinent encoders/decoders". Don't enable the in-kernel em28xx driver; it won't break anything, but you don't need it. I suggest you build the media-related stuff as modules rather than in-kernel; it'll probably make life slightly easier. Good luck, Aidan _______________________________________________ Em28xx mailing list Em28xx@mcentral.de http://mcentral.de/mailman/listinfo/em28xx
