I belong to a fitness forum and we hear lots of talk about workouts recorded to dvd-r decay, or can decay, within 5-12 viewings. I want to know if this is true and why because it doesn’t make sense to me.
It’s normal for fitness professionals, who don’t have a large market yet, to produce and sell their workouts on dvd-r. Savvy fitness consumers won’t buy them because they’ve heard so many stories about them degrading quickly. Some dvd-r’s don’t play in some players, we know that. But why would a dvd-r play well, initially, and then after a dozen viewings start to skip, not play, freeze, or have a lesser quality picture? It doesn’t make sense to me. It’s just a laser reading the disc, not anything that would cause “wear”.
So that’s the question. Why? Many people say it DOES happen so I can’t dispute that.
