I was under impression vdr-sxfe run with argument xvdr://IP.of.the.server should just work, which is not the case. How should I test streamdev plugin? I would expect it should be configured this plugin in vdr_flags... Also, what about femon plugin? How should it be used? On https://wiki.freebsd.org/VDR, there is some menu mentioned. When I use vdr-sxfe, there is no menu. Where is menu mentioned on wiki located and how could it be accessed? This is not clear at all from what's written there... Otherwise, it looks this device works well for usual watching, I need to find how to do some recording (not only pressing R key in vdr-sxfe) and how to play recorded program back. Regards, Milan
