When DVBStreamExplorer V3 is launched and another instance is already running one is faced with message below.
This limitation has been removed in DVBStreamExplorer V4 which has just been released.
Below is a screenshot from a Windows desktop where two instances of DVBStreamExplorer are running. One instance is scanning DVB-T data from a Cinergy HTC USB XS DVB-T Tuner and the other is scanning DVB-S data from TBS5925 DVB-S2 TV Tuner USB.
As a convenience DVBStreamExplorer application window title bar now includes name of capture device.
