I'm looking for a Universal remote to take over the functions of my cable box, DVD, A/V receiver, and TV. My concern is that I want the remote to be able to control the components functions (by selecting the appropriate component [TV, Cable Box, VCR]) but I always want the volume to control the volume on the A/V receiver. Will they do this? I'm looking for a reasonably inexpensive one. Earlier someone recommended the All-in-One Cinema 7. Will this one do as I described? Thanks!
