Be sure to finalize the DVDs.
Are you using a DVD player five years old or older to play the Verbatim +R discs?
Some older devices have difficulty with +R DVDs, especially those manufactured before DVD+R became widely available in the marketplace around five or six years ago.
The DVD Forum, a consortium of equipment manufacturers and others, first recognized DVD+R as an "official format" on 25 January 2008.
If you want wider compatibility use the original home-recording format, DVD-R.
