There is no such thing as OHCI HD capture card. OHCI aka FireWire is just a connection type.
OHCI comes for free nowdays...most motherboards have it onboard. As far as NX1, I think that's the NX board? If you use it's DV port, it is also OHCI so you can capture HDV, DVCPROHD, and other formats that support capture through the firewire connection.
The NX FireWire port is only OHCI compatible if you have the HD Expansion Kit installed and connected. (because the expansion board includes an NEC OHCI chip for ADVC functionality)
Otherwise, it is non-OHCI compliant (Sony iLink) - purely for DV/DVCAM equipment interface.
