Mind testing something?  

Go into tv_rec.cpp, and modify TVRec::RemoveRecording() (line 241 or so) to 

TVState TVRec::RemoveRecording(TVState state)
    if (StateIsRecording(state))
        if (state == kState_RecordingOnly)
            return kState_None;
        return kState_WatchingLiveTV;
    return kState_Error;

changing that kState_WatchingPreRecorded to kState_WatchingLiveTV, is all.

See if that helps at all?
