Can I record to a P2 card and an external disk drive, such as a FireStore, at the same time?
Yes, every P2 HD camcorder allows for simultaneous recording to its internal P2 cards as well as to an external recorder attached by 1394 (aka “firewire”) when recording to DV, DVCPRO, DVCPRO50 or DVCPRO HD formats. There are, however, a couple of exceptions due to the nature of external recording units and the 1394/firewire transport protocol. If recording using AVC-Intra, AVC-Intra doesn’t travel across the 1394 port and so a FireStore would not be capable of recording that mode. Also, when using the special space-saving 720pN mode, firewire transport is disabled so a FireStore or other 1394 recording device could not be used for simultaneous recording when in DVCPRO-HD 720pN mode.
