DVD-5

Since DVD-5 has single side and single layer, the artwork can be printed on the non-data side just like any CD-ROM artwork. Most DVD replicators will prefer the content be on a DLT tape, but also accept a ready to play burned DVD-R. 

DVD-9
DVD-9 is used by most Hollywood movies as an anti-piracy scheme. Although most movie will have CSS copy protection code embedded in the video, the biggest hindrance to copying is the unavailability of DVD-R for DVD-9. CSS can be easily de-coded and cracked. But you can only copy a DVD-9 on a DVD-9-R which is not only expensive but not readily available. (This situation may change quickly when the dual layered DVD-9-R become popular. But with the emerge of HD-DVD standard, manufacturers are putting a brake in making DVD-9-R more affordable.) 

Again, because of it's single sided, the artwork can also be printed as usual. Sending a content for replication DVD-9 is a little bit tricky then DVD-5. The most common way is to send two properly authored DLT tapes. Because DVD-9 has two layers so the play head of the DVD player needs to know when and where to jump from first layer (layer 0) to second layer (layer 1). For this to happen smoothly you will need to find the optimal layer break point. Normally a video editing company can handle this for you. Software such as ULEAD DVD Workshop and Sonic Scenarist can help set the break point. More and more replicators such ourselves begin to accept Dual Layered DVD-R as masters. The quality of the Dual Layered DVD-R is very important. From our experience, only 50% of the Dual Layered DVD-R can be used to make the glass stamper.
