Back in the day, I used a Sony FireWire adapter. It was either a DVMC-DA1 or DVMC-DA2, and either should work just about perfectly. I happened to be using it with a Panasonic 1980 video deck, but anything else would work jut as well.
Another good option is to use a DV camcorder that has an analogue input, which a surprising number of them do, I had a lot of good luck with a Canon GL2 for this purpose, but that may be somewhat spendy purely for video transfer purposes.
Another possibility is that there were SVHS and DV combo decks. JVC made one, for example. The big gotcha there is I don't know how long those really lasted.
I'd trust any of these more than most USB adapters, at least on old PPC Macs, and even doubly so on systems that don't have USB 2.0 or 3.0. I did a lot of DV capture on my blue-and-white Power Mac G3 back in the day. (Though, it did have a Yikes! G4 board.) I did some while booted to Mac OS X, but most of it was while booted to Mac OS 9, onto a cleaned-off 20 gig internal disk. Then I'd move the captured video to another disk for editing (either on the G3 or a PowerBook G4 I had), and then copy the finalized video back to the G3 to print it back out to tape.
