I came across Life With Solaris just the other day. It has a lot of the video applications that you might have grown to expect from an OS. Note that using these may violate laws or several other things depending on your location, so you need to use at your own risk.
It was pretty simple to add this to my OpenSolaris package repositories:
pfexec pkg set-authority -O http://pkg.lifewithsolaris.jp:10000/ video
and now I can access all their goodness. With that done I could do:
pfexec pkg install LWSvlc
pfexec pkg install LWSlibdvdcss
Now I can play DVDs in OpenSolaris. This is more significant than it sounds. A while back my dvd player broke in my laptop. Sony did a good job replacing it, but it was replaced with a Matshita drive (UJ-852S). And it seems that this has been impervious to my attempts to play DVDs on anything except windows. It turns out OpenSolaris is the winner in getting DVDs to play!
