Got to admit, I watched it on BBC1 then again on BBC HD and the difference in the volume of the background music was very noticeable. When people complained back in 2005, and every series since, about the music, I thought it was just because they were listening through their tv speakers and not a surround sound system, which I've had for years cos it really does make a difference when watching stuff. Even so, I would have never come out with a smart arsed comment like, "Put the subtitles on." I agree with Dave above, why should people who aren't deaf or hard of hearing, or trying to watch something when someone else is on the phone, feel the need to use subtitles to understand what is being said onscreen? They shouldn't. However, I suppose if they haven't listened to complaints about the music volume before, they're hardly going to start now. That's a shame because it really does make a difference, in my experience, to the enjoyment of the programme.
