Convert Hi-8 camcorder tapes to computer for editing

[dansof]

Help. I have a lot of old Hi8 analog tapes and Hi8-Digital tapes created with a Sony Handycam. (home movies). I want to get them into my computer for editing.
The camera has Svideo and RCA outputs. My computer has firewire and USB inputs.
Do I need an analog to digital capture device to do this? Do I need this sort of device for the digital tapes too, since no one seems to make a cable with Svideo on one end and firewire/USB on the other.
If I do buy one of these converters, what would you suggest? Will the quality be ok for home movies? (I want to be able to project the edited video onto a screen).
Thanks for any help.

You need a video capture card - this will come with S-Video and RCA inputs, you then play the tape in the camera and record it in the PC.

Available for less than £50 so not expensive. Hauppauge make them but I don't know if they are the best or worst, it's not really my area.
