(and I stress the words 'real > time') If the rest of my hardware is real time capable then the BT8x8 is. It even knows how to make sure you get partial frames in the event of excessive DMA congestion. Watching tv smoothly is a real time problem 8) If DMA timing is a concern, then it will be with any PCI based system, and you should perform your own PCI latency setups having verified that the chipset honours them properly, preferably is PCI 2.2 not PCI 2.1 and that the hostbridge does fair sharing including onboard peripherals - notably IDE. In the normal PC world "real time" is a bit limited. You can spend theoretical worst cases in milliseconds stalled waiting in the CPU because the exact worst combination of video card busy, PCI stall and write gathering cache writeout is occurring.
