Xiao Deqiang of the Mitk-Userlist pointed out, that users can not play files recorded using the IR-Mode of the Kinect.
The bug itselfs seems to be all about the file structure generated by the Recorder.
While all Devices need a DinstanceDataNode(ToF:needs Amplitude + Intensity-Node), depending on the selected AcquisitionMode the Kinect generates either a RGB or an IR-ImageStream.
If selecting the IR-Mode, there is no respective DataNode.
A fix should be to modify the recorder to check for RGB or IR-Properties of ToFUtil and to add a "kinect"ending tod the saved files. This should permit us to play the IR-Files saved in the "AmplitudeImage".
