Annoying thing happened this evening. Wife and I were watching Grand Designs (Ch4) but due to a Tea & Coffee break had it on time slip. We had no other on going recording but at 10pm (also CH4) I'd set a timed recording which once commenced brought us out of the time slip and up to date thus losing the end of Grand Designs. I just automatically assumed the HDR would use the other tuner for the recording and leave us be. That needs addressing.
