Back with the same problem. 6 streams of HD avchd. This concert will not be a Blueray. Should I just downscale to SD to edit. Basic question im lost. My Mac Pro is a duo quad 2.8 with 4g of ram, I don't have to luxury of putting a Thunderbolt drive to get the 10g rate and I think the next fasted would be eSata at 5g. Please some kind of help would be great Im getting conflicting advice.
