Same Problem here ;-) The Remote also does not work on my BIG PC with the HVR 1110. But it did work as i bought the Mini Stick. Mini Stick was connected to my 32bit Win7.
tried already a new baterry, but this was not the fault.
I thought i am the Only Person with this problem. But it dont looks like so.
As i remember the Problem was already in 2.5c maybe before too.
