That is the notice I would see if I started to play a show that was not yet processed. When I recently installed DVRMSToolbox, the add-in and SAV1, that's what it said when I started to watch any show that was recorded prior. It then asked if I wanted to process that show, so it would skip commercials. If I said Yes, it would process the show and I could watch it commercial-free later.
Bye.
