DVD-RW discs can be used as Video mode discs or VR mode discs. The
difference on the DVD recorders is they create Video_TS on Video mode discs
and have an additional Video_RM or Video_VR folder in VR mode.

DVD-RW must be finalized to playback on other machines, and the playback
percentage for other machines is greater than non-finalized DVD+RW. DVD+RW
recorders offer the option of "protect" on a disc which halts further
recording on the disc, and when this option is in place the likelihood of
playback on other machines is greater than those not protected.

The +R recorders always have the Video_TS and Video_RM folder present. When
duplicating these discs to -R copy the contents of the Video_TS folder to
the Video_TS folder in a program like Nero Burning Rom and then drag the
Video_RM folder to the disc root.

Using this method works 100% of the time while using DVD Copy fails about
75% of the time. I speak from daily reports from the business mentioned
earlier. As a part of my assisting them we conducted tests using these
procedures.

Since they did not want to get rid of their Philips recorders the practice
of using DVD+RW was instituted. That way the recorders could be used without
wasting discs since the RW's could be re-used.Once the disc was recorded to
it was then placed in a standalone duplicator to be copied to DVD-R. When
reaching the end of the duplication process a failure would occur, thus
ruining a disc.

Instead of using the duplicator for this process they then would copy the
contents of the disc to a folder on the hard drive. They then opened Nero
Burning ROM and chose DVD Video as the setup. Once in the program the
contents of the Video_TS folder on the hard drive was dragged to the
matching folder in the project. They then highlighted the disc proper in the
project and dragged the Video_RM folder to the project. There was never a
burn failure using this process between August 1, 2005 and December 24th,
2005. The failure rate was, as I said before about 75%. This information was
gathered from keeping all the failed discs out of over 3000 discs used
during that period.

For the machines using DVD-R & -RW the RW discs were used for the same
reasons of re-use, and the duplication process of these discs only failed
about 2% of the time.
