Do you think that the video format war for the DVD will be over soon?
I still do not see that one format is overpowering the other. I have a
few questions about these formats
- Which one was the one first to come out?
- When you buy a DVD movie from a store. Is it a DVD-R? It has the
same symbol as DVD-R (The DVD+R symbol just a box with RW written on
it). The DVD movie, as well as DVD-R has the disk picture logo on it.
- Is dual layer DVD applicable for both the DVD-R and DVD+R?
- In the past, some movie's DVDs were written on both sides (sometimes
one language on one side and another on the other side). Could you buy
such a DVD in the market?. Do you have to have a special device to
record or to play?
- Technically, which one is more superior? DVD-R or DVD+R ? If DVD+R
came up later than DVD-R, did it means better and newer technology?
- Is it technically more complicated to produce a DVD recorder which is
capable to handle both DVDs? Or, it is just a simple switch technology
inside the box. If this is the case, then those DVD producer must have
vested interest with one type of DVD over the other. My LiteOn brand
DVD recorder is cheap (now under $100), and has the convenient to to
both? Why not other manufacturers follow suit (except for those who
invested one format over the other).
I seem to notice that DVD writers for computers appear to be accepting
both formats more readily than those stand alone DVD recorders/players
to record from TV.
- When people invented CD-R or DVD disk years ago, they indicated that
using the CD or DVD technology is different from a music/video tape, or
LPs. Unlike those other old cassette, LPs, there is NO contact when you
play a Cd or DVD. However, I notice that CD and DVD have lots of
scratches after a while. How do these scratches created?
- Final question - where do you find a DVD disks that guarantee that
the recorded data will last a long time. Is there a special DVD (DVD
gold or something) that can guarantee the data will not disappear
(permanent) after it is recorded. I seem to only notice one type or
grade for DVD disks, but I may be wrong.

I know that these DVDs may be replaced with either Sony's Blu-ray or
the HD-DVD. However, I still do not see that DVD-R or DVD+R comes as a
winner, unlike the battle between Sony Betamax and VHS format. It is
more convenient when you look at CD-R, there is only one type available.
