I started with an early version of Popcorn and found it lacking, and a real bare bones tool, perhaps the upgraded Popcorns are moer feature rich? I bought Toast, which I continue to use almost daily as it is chock full of useful disc creating software like the ability to create disc images and burn MP3 discs and data discs of a great variety. Toast also came with a great CD/DVD labeling product called Discus, which I have upgraded over time and use extensively for high quality CD/DVD art work copies or creating originals. Think Roxio switched to another labeling system intro version, and don't promote Discus any longer. I didn't care for much the new Disc Art sw they had on Toast.
I don't think there is a better labeling software for the Mac user, let me know if there is something better? SO, get Toast anyway if you plan on burning discs, or creating disc images as well as burning TS files to DVD. And if you don't need Blu Ray support yet, I think you can downgrade a version.
It's full of lots of great Mac DISC software of all kinds. I prefer it to burning discs with iTunes only and it generally integrates with iTunes well. (for the most part)
Toast is a a nicely put together suite, with a good user interface which is fairly simple or as complicated as you need it to be.
I keep getting offers from Roxio for highly discounted Toast versions, so I'm sure it is available for less than full price.
The one experience with Handbrake took me a long, long time to encode, but that could be my old equipment. I have dabbled with Mac the Ripper and it works well with older stuff. If you have the patience to jump through the hoops to contact the author and get an UPDATED version, which gets more and more intricate.
I think it's just about to the point where it may require less energy to just purchase another disc copy than to deal with frequent anti copy iterations that can turn a whole lot of time and work into a coaster. Be prepared to keep up on all the latest snags and then run into frequent glitches with long waits for a fix. I don't have time for that anymore. I don't even have enough time to watch the few movies being produced these days that would be worth buying in order to back up.
