Last night I left my box on with my OK2 sub running and programmed to record a show. This morning I was watching something using my IPGuys sub. When it was over I clicked on PVR to watch the show recorded last night but it was not listed. I then switched back to my OK2 sub to watch Sports Centre. Later when I clicked on PVR the show I recorded last night was there. I take it that PVR recordings are stored with some link to the sub from which it was recorded.
