What type of content are you looking for?
If you are looking for TV or movies, that is actually quiet easy. Ironic that it is easier to schedule the downloading of copywrited material vs. legitimate streaming material.
If you are referring to public, streaming content like Youtube, then there are lots of freeware and online converters, but setting up a schedule is 'probably' difficult. Got any Pearl programming friends??
Here is an online tool I used for Youtube but is looks like it has a lot of other uses as well.
www.convertfiles.com For instance, you can enter a Youtube link and it will download the youtube to its server somewhere, convert it and then email you a URL to go fetch the resulting avi file. I used it just once when I just had to have my own copy of "Ultimate Dog Tease." It worked well.
I have seen software advertised for Netflix and other subscription services but have no experience with it.
[Edit] Looks like you found some while I was typing.
