Hi all,

I am still working to improve the vdr-plg-dxr3 and I run into an issue. Lets say I watch TV but there is nothing interesting to watch, so I want to playback a recording. But this happens now in the plugin:

As you can see the video pts is for some time increasing to about 1079487. And then suddenly it changes to the correct value of the recording. I assume that vdr does the following:

Is this a bug or a feature of VDR?
