Very good Question, Philip! But the answer is yes, the OS is on NTSF
It may be worth noting that, when using 'Edius 5' Software instead of the DV Storm Software, the capture time is only limited by the size of the Hard Drive, but the catch is that I am then forced to use a OHCI DV Port because Edius 5 does not support the use of the combined input/output ports of the DV Storm. Whilst this enables me to capture DV, it prevents me from capturing analogue sources (unless I invest in an intermediate converter, which I don't really want to do)...
Thank you for your thoughts!
