I didn't like most of this post, talking about what some of these folks think Apple execs like or don't like. I thought it was a waste of time so I did some research and was given the following reply, which might help with what you are looking for. I know Discussion groups like to pontificate. I'm not saying that's bad but I just felt many were missing the mark.
"Whilst Macs with a Superdrive continue to be able to burn video DVDs, the software for so doing, iDVD, is no longer included in the iLife bundle that comes with OS 10.7 Lion (which also omitted iWeb) or will come with OS 10.8 Mountain Lion. And it is no longer included in the iLife 11 from the online Apple Store: http://www.apple.com/ilife/. Your only solution is to look on Amazon or eBay and try to get an older version that includes iDVD 7, i.e. iLife version 9 onwards. You should also do this if you plan to buy a new Mac anytime soon, as stocks of iLife that include iDVD will not be available for ever.
However, the vastly more expensive FCPX can burn a DVD without iDVD or DVD Studio Pro involvement, but lack the themes etc of iDVD. Also, of course, there is Roxio Toast, which is the best software for burning anything but again does not offer the flexibility of iDVD."
