Hi Lars, Some results from further testing: - "live viewing with switching channels between frontends": Works OK, with about a 3 second delay switching from terrestrial to satellite and about 10 seconds going the other way. The timings are pretty consistent and I put the difference down to the time to lock being significantly longer for satellite. - "timer recording starts while viewing live TV on the other frontend": Seems to behave reasonably. The screen goes blank and eventually the picture is replaced with what appears to be that of the first channel on the transponder that we are now recording. It stays there even after the recording completes. The same behaviour is experienced when going either way, e.g. viewing terrestrial when satellite recording starts or viewing satellite when terrestrial recording starts. Have not played with timer conflicts yet. Now, the problem: It's broken a number of plugins which no longer compile. These include dvbhddevice, dvbsddevice, dvd, osdpip, Rotorng, sc and upnp which I use but I'm sure a number of others will be affected. The primary reason appears to be the redefinition of cDvbDevice, but some other errors are also reported. Is this redefinition the 'dirty' part of this initial attempt, or is it fundamental to the approach? If it's the latter I suspect it will be very problematic for many users of affected plugins as these will need to be modified to conform.

It may be (since the device hasn't changed) vdr is thinking that it's showing an available channel or something like this. > I'll be playing with it in the next couple of days including > introducing a SD premium card into the mix to see what happens. Is > there anything in particular that you would like me to try? I haven't made too much thoughts about tests. Maybe we can work on a checklist together. use cases: - live viewing with switching channels between frontends - timer recording starts while viewing live tv on the other frontend - timer conflicts with different priorities on the different frontends - streamdev-client/-server? - ...? It looks like the HVR 4000 has no CI. At the moment I don't have access to cards with decryption hardware, too. And I'm not too familiar with this part of the vdr (ci/cam etc.).
