I found two Radio Shack remotes with codes for your TV, VCR and DVD. None for Duraband, though.

The 15-2115 sells for $10, but I think it is discontinued, although it may be available somewhere.

The 15-2116 is available, but it sells for $32. The good thing about this remote is that if none of the codes work, you may be able to get it upgraded.

Each had several codes listed, but if they don't work the remote is easily returnable.

The OneForAll 6131 is available at Walmart and also has codes for the TV, DVD and VCR. I don't remember the price but I am sure it is much cheaper than the 15-2116, so you might give the 6131 a try if you can't find a 15-2115.

The 15-2116 and the 6131 are also capable of using advanced codes, so if some functions are not preprogrammed, you could most likely obtain these functions through the use of the advanced codes. One of these two would probably be your best bet considering cost and the ability to control your components.
