Yes those will work. I'd stick with the Hauppauge model, they are a better brand.
Just make sure you calculate the video file size and format vs quality, how long you are recording for and the space you have so your drive does not fill up and the PC crashes while you're away.
Thanks yes, I'm sure I'll have to play with that. I just didn't want to order something that wouldn't work. I think they are only 320P, so hoping the files aren't that huge. I'll probably only be able to keep a week at a time.
