Mr Newbie here..........
Had my HDR T2 for about 18 months now.
Suddenly it's proving difficult to operate with the remote and I notice that quite often the function buttons (PVR- TV- DVD-AUDIO) light up in sequence when I push other butons.
You were lucky - I had to change the batteries that came with mine after about 3 months. Mind you they were not alkalines that came with it, but they got replaced with alkalines. Been going strong ever since, except for some dicky buttons that need the top rocking to make them make contact and operate.
