Should any DVD manufacturing facility only be able to offer the duplication of a
DVD-R supplied along with the printing of a j-peg for example, while they are likely to be providing cheap prices it is also likely you will end up with cheap result and possible playback problems. The authoring can be complex subject to your needs and just because what you create plays fine on your system, doesn't always mean it is OK for any system. Before going for DVD manufacturing, the more tests that can be carried out and the better checks by your chosen DVD manufacturing company the better to be sure of avoiding problems.
