In effect, the video capture is on it's own PCI bus. It's not actually a PCI bus, though. It's a bridge chip on the CPU/Memory bus. So, the Bandit PCI Bridge is a device on the CPU/Memory bus, and the video capture chip is also a device resident on the CPU/Memory bus.Finally found a really nice 8500 semi-local and cheap. After the usual UV treatment to bring the plastics back to beige it will be like new.
Does anyone know if the video capture circuitry on the 8500 shares bandwidth with the PCI slots?
So video capture isn't going to interfere with PCI bandwidth, except to the extent that anything which takes CPU cycles/attention also takes PCI bandwidth.
