Sima's SUR-20 is compatible with all of the brands you listed. If the preprogrammed codes do not work for your models you will need to use your existing remote to teach the SUR-20 for that device.
It is sometimes possible to program the volume control for your TV on another screen but the devices would have to be the same brand and the remotes would have to be using the same frequencies. If this did not work there is an easy solution, for example: program the volume keys on your VCR screen as macros (any button for all of the screens can be use for a macro) for the volume up/down keys on your TV. You can even go as far as using one macro to increase the volume on your TV and A/V receiver at the same time.
