Slysoft has announced that, as of January 01 2011, they will be discontinuing their lifetime update license for AnyDVD and AnyDVD HD. However, a quick check shows that it is still an option on the sales page.
So if you have been playing around with their trial versions and thinking about getting a registered license, I would HIGHLY recommend you do so immediately before they pull the lifetime update option for good! AnyDVD HD is honestly the easiest solution out there, works absolute wonders for blu-ray, and is definitely well worth the money.
