I generally just capture to the SDHC card on my AVCHD camera. But as I have started using the AVCHD output more, I have learned a few things that seem to make it a huge advantage over HDV cameras 1394 output.
I use the HDMI output for monitoring off my AVCHD camera. HDMI output is uncompressed digital, so the image quality is exactly what the imager sees and great for uncompressed capture. A 1394 TS off a HDV camera is a highly compressed 4:2:0 digital signal. The HDMI uncompressed signal is 4:2:2 colorspace which is great for keying. HDMI also supports cables up to 20M in length and 100+M is possible with special equipment.
A lot of folks seem to be using the BM Intensity Pro card for HDMI capture. Blackmagic Design: Intensity (http://www.blackmagic-design.com/products/intensity/) Seems like a good option.
