I swear by slysofts stuff, http://www.slysoft.com/en/ Their products are spot on. I can play, copy and send to my iphone anything I have ever thrown at it.
AnyDVD runs in the system tray and intercepts all DVDs and rips out the encryption and region coding on the fly, so your PC always sees an unencrypted DVD.
CloneDVD copies any DVD I have ever asked it to.
CloneDVD mobile will rip it and convert it to anyformat for use on a portable device.
Theres cracked versions out there, but I have been so happy with them I paid for them and get regular updates. I've been using them for several years and there hasn't been a single issue it couldn't handle and very much plug and play.
As for the other question, turning downloads back into DVDs, theres a few out there. I'm away from home right now and can't check which one I'm using, try a google search, but again theres plug and play ones out there that work like a dream.
Edited to add, I'm sure slysoft let you trial their stuff for 21 days so give it a go, you will never look back.
