The original Beovision 1 (and Beocenter 1) were controlled by the Beo 1 remote. They then changed to Beo 4 later. The Beo 1 is a fabulous design but relied too much on the TV menu to work. If you aren't using the TV fully then the Beo 1 will probably do for you. They go for under £30 here in UK.
technov1king, I just re-read your post, if you have the built in DVD, then yours will be a Beocenter 1, and the Beo 1 will control the DVD.
