I've been looking in to this a bit myself lately and it is like there are too many options and ways of doing this, internal or usb capture cards and devices, these devices offering a variety of features and options and quality.
I ended up going for an internal capture card wintv hvr 1100 from hauppage.
My main purpose was to transfer about 20 hours fo analog video, I could have got a usb widgit just to do that but what do you do with the thing after you are done? So I opted to add PVR functionality to my PC so I can record TV and stuff, with this particular card freeview also.
The DVD recorder option is aparently a good one, and if you only have a few hours to transfer the best option is to find a friend who has one and borrow it.
You end up with a DVD that you can then rip to your pc, edit then rerecord.
I read somewhere, I think on click here, that the technology for transfering analog to DVD in these recorders is as good as just about anything on offer without spending serious money on some sort of highend capture device.
