FWIW, I have the following setup and I have no problem with capture:
MacBook Pro 15" (Snow Leopard, the new MB Pro with the SD slot)
Seagate FreeAgent 1TB External HD for Time Machine (two FW800 ports)
Canon XH-A1s (the new version with the 6-pin FW400 connector)
FCP 7.0.1
I chain the camera from the external HD with a 9-pin to 6-pin cable, and I capture to and edit from the internal 500GB HD (7200RPM), and the system works flawlessly.
I have never had a problem capturing, but as somebody said earlier, you MUST make sure your Capture Preset and Device Control Presets match the mode your footage is in. In other words, if the footage is DV, choose DV NTSC 48kHz/Firewire NTSC; if the footage is HDV, choose HDV/HDV Firewire. Also, I use the "auto" mode for playback in the camera.
BTW, I have also connected the XH-A1s directly to the MB Pro with the 9-pin to 6-pin FW cable and that worked fine too.
Just putting it out there for people considering a similar setup.
