I like video for the way it captures movement. You get a better feeling for the personality of the individuals from the dialog shown by their body language. The sound of someone's voice is also a unique memory trigger.
Having said that, I think that video is a poor substitute for a wedding album. Before anyone gets in an uproar over that statement, video makes a great addition to the wedding package.
The reason is that I think that Photos are better is that they are more stable, durable and intimate.
Stable in that a photo should last a 100 years or so with minimum care but a DVD/CD may or may not work in 10 years. The supporting hardware/software may not be around then or not be working and forgotten.
Durable in that you can bend a photo, tear a photo and very nearly burn a photo and still be able to use it. Not so with a DVD/CD, they are unusable with just scratching. Keep a backup? Please, most people won't back up their tax info much less keep track of a DVD for the next 100 years as an heirloom of their house.
And intimate? You can't hold a TV in your lap, a laptop yes but the CPU in one of those has an operating temperature of 126 degrees F. and is uncomfortable at best. Being able to sit with your children or grand children and show them their family or that you were really young once.
You can also do a survey. Ask 50 women who have been married at least 15 years if they or someone they knew had been in the process of deciding on a divorce and looked through their wedding album which caused them to rethink the divorce and subsequently decided against it. You are likely to be amazed how many have or know someone (which I think may mean that they have and don't want to admit it) who has done just that. (Again, not something that is done with a TV)
Friends and neighbors, I promise you that a wedding album is
much cheaper than a divorce.

Tell
that to someone who thinks that wedding photogs are over paid.
