i have factory installed on c: drive which has 15 gigs free
and i'm trying to capture 45min of video via fire wire to 
my d: drive which has 60 gigs free
it captures at 400mb per minute which is plenty of space
but when i open the capture window it says i only have 18 
minutes of capturing space available
maybe i'm doing something wrong in the set up of the 
capture , i'm not sure
looking for answers 
thanx
todd
