The VP415 LV-ROM player has sophisticated facilities for controlling disc playback, either via the remote control or by programming the player from an external computer. The VP415 also has a number of video mixing and overlay modes which are used extensively by the Domesday Discs. All these facilities, however, are available from the player no matter what disc is playing, as they are built into the player's internal control software. This section explores this important aspect of the LV-ROM player and I hope you will click on the picture links above to see more.
