ExternalRecorder plugin - configuration question

[fgomes]

I have installed the ExternalRecorder plugin to record using ProgDVB. I still have some doubts:

What is the purpose of the PreviewParameters? When are they used? I suppose that when I shedule a recording it uses the RecordingParameters... In these I put the channel number and filename and it seems to be working (at least progdvb is called and a recording is made, but no gui from progdvb is shown and the recording only apears in the final location when it ends, I don't know where it is saving it during the recording session).
The preview parameters is for LiveTV? Shouldn't it also make a recording in order to be available to the mediaMVP box, or it is not compatible with mediaMVP for LiveTV? Is it only supposed to open locally (on the PC) the external application, or there is a way to see this program in the mediaMVP, using a temporary recording file, as for the 'normal' LiveTV on the mediaMVP?

Thanks!

Is it possible to use LiveTv in MediaMVP with the ExternalRecorder plugin? When we select live tv for a channel from ExternalRecorder, the gbpvr waits for a specific file with the video, like when we select a channel from the internal card (PVR50 in my case)? Thanks. Fernando
