Is that because it might do some damage to the card, or to the host computer, or both?

Ah yes, I've just found that, it seems a little pricey! There is also a listing for an "Avermedia 4 Eyes Pro Capture Card PCI 8604" which looks pretty much the same, but it doesn't have any software with it and searching around for any more information on that hasn't got me anywhere. I've just been trying to make my card work under Windows, but no luck there either. I didn't get a driver CD with it, Windows 7 doesn't autodetect anything for the video chips and when I tried to frig some drivers I found earlier today for a similar looking card they did install, but then didn't work - the not very helpful "device failed to start" error you get in Windows. Which I guess means it's just not the right driver. Shame, but I think I'll just have to chalk it up to experience - it wouldn't be my first duff purchase in the video-capture-device-for-linux area :-) Thanks for all your efforts. Cheers, Rob.
