run_pvr_scheduler.bat does the following:

cd C:\Program Files (x86)\get_iplayer
perl.exe get_iplayer.pl --pvrschedule 14400

If I terminate with Ctrl-C it seems that I need to go delete the pvr_lock file manually before I am able to (a) run the batch file again or (b) Run the PVR from the GUI on another machine. Am I doing something wrong?

That happens when the perl.exe process that created the pvr_lock file is still running. No idea how you managed that, but you should be able to kill it from Task Manager. If it is not running, a new pvr_lock file will be written on subsequent invocation.

My mistake... I realize that I had not terminated it normally.

It was during initial set-up so I was fooling around and not really thinking it through properly.

Thanks
