Any advice on viewing a demo DVD?

When you are viewing demo wedding video you must be careful. I have found that some videographers use other person's work as their own. That creates false impressions on how that person's work is. I always give my clients the option of choosing out of about 20 resent and maybe 3 or 4 older that 2 years wedding videos . They can pick any one of the DVD's . By doing that, I show them that I don't only show them my VERY BEST DVD. They can see my style off recording. They can even sometimes ask for a specific VENUE and I might be able to show them how it looks there. Once again eliminating the chances of just showing the best Video. By doing this, I also show them that all our wedding DVD's are the best!
