I had the same problem with my canon xha1, I finally capturedd some footage. I have FCP 5.0.4, my settings are as follows, on the seq presetI used DV ntsc anamorphic, capture preset HDV, device control, HDV Firewire. I shot in hd, but keep the sequence at dv ntsc. That might help and everything captured perfectly. My problem is that i cannot edit in real time, I have to render everything, the audio, clips, etc. Do you have any suggestions on that?
How do you like your camera? Is theri a fourm on video cameras like the one we purchased the canon xha1. Hope fully the presets help, good luck.
