They are getting older and are having trouble remembering how to switch to the various devices they have.
Currently they have the following
Keep their existing TV
Allow them to use one remote
Not spend a lot of money on this.
I haven't yet actually looked at the back of their TV but I'm guessing that it has RCA and Coax inputs (I'll confirm this weekend.)
My guess is that the DVD/VCR combo might be what's confusing them and that it might be easier for them to have separate devices and a basic universal remote that would allow them to switch between TV, DVD, VCR.
If I get them a universal remote it has to be very simple. Too many buttons will confuse them.
Or is there a better way? (ie, AV receiver that supports this older hardware?)
What I'll do first is to figure out how their current system works (I really haven't looked at it yet) and to write down clear instructions for how to switch between devices.
