To record video (and audio) to DVD, make sure you use blank discs that are compatible with your DVD recorder or PC-DVD burner.
DVD+R and DVD-R; how did that go again?
Before you can record a TV show or transfer camcorder tapes to DVD, you'll need to purchase a blank disc. Blank DVDs can be found at most electronics and computer stores, and can also be purchased online. You can purchase a single disc, a few discs, a box or spindle of 10, 20, 30, or more. Some come with paper sleeves or jewel box cases, but those packaged in spindles require separate sleeves or jewel box cases.
As mentioned above, you will need discs in the correct format that are compatible with your recorder and that will also be playable (after recording) on your DVD recorder and DVD player(s).
If your DVD recorder records in the DVD+R/+RW format, make sure you buy discs that have that label on the packaging. You cannot use a +R disc in a -R recorder or vice versa.
