One of the primary purposes of Newsome.Org is to introduce and explain computer-related programs and features to other in-betweeners like me- people who are the parents of the youngsters to whom computers and the internet are as integral as the telephone and the children of our parents who have no intention of ever embracing computers.
Everyone, no matter what age, has a DVD player and watches DVDs. Many people record TV shows and/or home videos onto DVDs. One problem with recording DVDs is that, because of conflicting and sometimes incompatible formats (DVD-R, DVD+R, etc.), DVDs recorded by one player won’t play in certain other DVD players. Fortunately, many newer players can play most, if not all, of the current DVD formats (older and very low end players still cannot). But the problem is about to get worse.
Like about every other emerging tecnnology where there is money to be made, various companies are pushing incompatible new DVD formats for new, higher capacity (i.e., can hold more video) DVDs. C|Net has posted an article that tells you everything you need to know about the HD DVD vs. Blu ray compatibility war. If you use DVDs and especially if you record onto them, you need to understand this issue and how it may affect you and your videos.
