Do you mean home video or what? I burn DVD video of home movies to send my parents of the kids... but I use an older Samsung VCR / DVD recorder combo with a firewire port. I have done it with software on the computer, but I gave that up, it's just too quick and easy to burn with the Samsung from my camcorder.
I use to order certain dvds from Netflix just to record them on dvd. I'd prefer to have the original copies but most were waaaay over priced on Amazon since they were out of print. The bulk of them were 1970's Saturday morning live action kids shows like The Ghost Busters (featuring Larry Storch & Forrest Tucker), Space Academy (Jonathan Harris), Monster Squad (with that Gopher guy from the Love Boat tv series), etc.
Far as I know they'll still play but the longevity of recordable dvds is suspect and I have had my share of recorded disc failing to play over the years.
I've had to burn a few over the years (for things like school / work projects - not for pirated movies). But even burning CDs was always such a hassle. By the time the tech became commonplace enough that I might have used it more often, there were better alternatives like streaming becoming available.
One thing to note is that you can't leave recorded discs out in the sun.
I've been using a video capture device to digitize my VHS tapes and storing them to my hard drive as MP4's. I've also used the MP2 versions to burn DVDs of stuff like "Jake Speed." I may even see what interesting stuff I can find on VHS just for fun.
