By default, the only visible indication that a recording is in progress in standby is a very small and dim REC icon on the front screen and even that doesn't appear if you have power saving turned on. It has been a commonly requested feature to be able to see when a recording is in progress. I've read that early versions of the firmware did change the LED ring colour when recording in standby but that this was subsequently removed. The redring package changes the behaviour of the LED ring in three ways: when the box is in standby but waiting for a recording to begin (AR mode), the ring will change to blue colour, just as when the box is on normally (the LCD screen will remain showing a clock or blank depending on your power saving setting); when the box is in standby and recording, the ring will change to a bright red colour, just as it would were the box fully powered up; when the box is recording two programmes, the ring will change to a purple colour. This is a test release which still has some known bugs: Sometimes playing back a recording is interpreted as a recording and the ring turns red; A race condition in putting the box into standby can result in the ring going blue while the box is off; This package can occasionally cause failure to wake up for recordings.
