Hi

Thanks for the idea.

I forgot to tell that in my case the PVR Server and Kodi frontend are both in the same PC, so I´m not sure if checking the network/internet is relevant...

Is quite weird all in all. When the PC is just started up, if I try to open the Windows Services panel, it won´t until some time (too long to be normal in my opinion) is elapsed.

During this time, PC apparently looks like ready, but many programs don´t work. 

It might still be relevant - I've read dvbviewer-related problems where the client is pointed at 127.0.0.1 (ie same machine) and it fails if the network's down.  But if not if you could find a condition that does work you could swap that into the script.
Edit: or is it just a case of waiting for the server to start up?  That's easily checked for, it's what the second line (tasklist | find /i "kodi" >nul 2>&1) is doing.
