DVCPRO HD will play back over firewire but I had some drop out’s with capture (25p) but if you are planning a film out I would recomand Photo-jpeg because of full raster and try different quality settings that will sufice.
For capture you may buy firmtek pci sata external cards and enclousure for 2 hdd for all editing stations and do a raid0 then you can move the disks between stations, it is bit more expensive but will save you a lot of trouble
