Klaus Thank you Klaus for your offer and your effort. I guess this is one of the bugs (not necessarily a vdr one!) which are relativley hard to track. Yesterday i have reproduced the issue with a vanilla vdr 1.7.27 and the only plugin being xineliboutput to minimize potential bug sources. I did not observe any changes, the issue still appears. My setup: debian squeeze self-built Kernel 3.0.4 media-build git20120504 vdr 1.7.27 Technisat Skystar HD (PCI DVB-S2) - clone of and recognized as Technotrend S-3200 (stb0899) KWorld DVB Satellite card - clone of Twinhan VP1020 (PCI DVB-S) WinTV Nova T-Stick (USB DVB-T) xineliboutput cvs20120415 vdr-sxfe with vdpau on a 8400 GS PCIE nvidia driver 295.40 Satellite setup: One satellite cable that is being distributed with a splitter (diode protected). No priority circuit afaik. In vdr both devices are set to be connected to cable 1. This is a Diseqc setup and Astra 19.2E and Hotbird 13.0E are receivable. The rest of the setup remains unclear yet most likely the cable goes to a switch or something though surely not directly into the lnb. Symptoms: AV signal sometimes stops while watching a DVB-S(2) channel (T not tested). Concerning the log this most likely happens when vdr fails to tune to a channel while scanning for new transponders in the background. Device bonding then tries to make another tuner tune to this channel which in this case obviously is the liveview device. This not only freezes the liveview AV but also makes recordings stop to

Master in my assumption should be the device where the liveview signal comes from unless there is a recording in which case the device tuned to the recording transponder should be Master.

Both devices were even capable in the former 1.7.21 dual device setup (with my patch).
