canceled recording doesnt free up tuner

[fuzzweed]

we're watching live tv when two scheduled recodrings start up together (on my twin tuner system) and we're dumped back to the epg - deciding that we'd prefer to keep watching live tv we hurridly cancel one of the recordings ("tripping over" at 22:00) and the epg bar goes from red to green, but gbpvr still doesn't think there's a tuner available. I double checked the the pending recordings screen and it only shows the one being recorded. Howeveron checking the status via the gbpvr tray it showed both tuners still assigned to the scheduled recordings.
My balls were only saved by my emergency work around of sticking the aerial back into the TV set
Any help to prevent this happening again would be appreciated, as I was bloody lucky that the channel w/she wanted to watch was on analogue.
logs attached.......
