Here is my tip (and file management).
Use a separate card (or 2) for each days shoot.
(I only use 16GB cards mainly for this reason.)
The issue with AVCHD (AVCCAM) is that the file numbering repeats. eg always starts each card at 0000.mts - xxxxx.mts ( even "00000" is weird!)
I ingest them to a unique 'rushes' folder eg Rushes projectname Day 1, Rushes projectname Day 2, Rushes projectname day 3....
The backup drives and the archives have the same naming protocol.
For the actual transfer of files, just use Finder. You don't need any special software.
Thanks guys, I appreciate the tips. I love the naming convention, I was considering doing the actual date, but with metadata I guess I don't really need that. I think we will use finder, though I'd still love to have some software for ingest similar to what they've done with FCPX where you can scrub, select and ingest just what you want right from the card. Unfortunately it does a bunch of other stuff with the footage, rewrapping it in a funky way that Premiere doesn't like, changing the name prefix, etc. Since we had a copy for evaluation I had toyed with the idea of using it just to get footage in. Oh well.
