shows how to set up custom post-processing, kicked off after the recording in finished.

is there a way to kick of a custom task just after the recording has begun?

i want to run a custom script just after a recording starts.

thanks

edit: my script will
1. unhide the file being recorded so that it will be visible to a network media player (and can be played/streamed)
2. refresh the tversity upnp server so that it's library contains the newly started recordings

the script works fine manually............just need a way to kick it off just after btv starts each recording.
today, i have windows scheduler do step 1 at 00:01 minute after each hour and step 2 at 00:02 minutes after each hour.
this activity, whether or not there is a recording, will keep the pc from being in standby and wastes power.
i'd like to kick off these actions only when necessary
