I find that DVD-R dvd's aren't reliable and it comes down to what software is used for recording it.
My bro has one from his racing school and it doesn't always work on the TV
dvd player, it seems like they used a cheap recording software for it.
Other than that, I have one from A&E store and they have good recording quailty DVD-R and seems fine.
I like the ones that comes with movies such as Air Force One, etc and they're recorded professionally but they're expensive, anywhere from $15 to $30.
I can tell the type of DVD they use. The DVD-R are purple on the reading side.
The movies DVD have clear reading side and looks similar to music CD
's you buy in the store.
And those bull CD
-R portrayed into "DVD" have a light green reading side.
