Dynamic Instruments (DI) has developed an external DVD drive, interfacing with DI's Enhanced Courier to provide laptop playback of DI archive media disks on Windows 2000 Professional workstations. Laptops or workstations are easily converted to a mobile recorder playback station providing users with stand-alone audio replay, network independent audio duplication tools, court replay of original archive media and court replay of archive disk copies. These are just a few of the applications that can be addressed by installing DI's powerful Enhanced Courier software on a workstation/laptop and connecting the external DVD drive via its USB connector. Later, the external drive can be removed and stowed at the conclusion of a local DVD playback session.
