- DVD+ and DVD- What is the difference after burning which makes DVD+ somewhat incompatable?

Haing faced this problem, why is a DVD+ disk less compatable than a
DVD- and why?????

There is a apparently a book type table at the start of a disk which says
what type of disk it is eg DVD Rom or DVD+R. For +R set top recorders disks
are typically always set to DVD Rom for maximum compatiblity. For PC
recorded disks +R is typically set to DVD+R and as a result is less
compatible with some players.
Many PC recorders allow compatibility bitsetting via a utility or as part of
Nero which forces the the disk book type to be set as DVD Rom
In my experience bitsetting helps. I had an old creative PC dvd drive which
wouldn't look at any recordable DVD except for a +R that had been bitset.
I'm not sure why everything isn't just set to DVD Rom straight off but it
may be to do with features that +R can offer provided the player nows its a
+R.

-r disks came first, and have been around longer.

dvd-r been around for years longer than dvd+r which is why more
players prefer dvd-r over that of dvd+r.

That's pretty much a moot point though, as few people still have players
that are over 4 years old.

The most common reason for the incompatibility is that the older DVD
players look at the header, which tells the drive what kind of disc it
is. Some of these early players would know what to do with DVD-R and
DVD-ROM (this is essentially what a pressed DVD movie is). It might
assume everything else was some sort of unsupported disc format like
DVD-RAM (which won't play on many DVD players either). It sees the
DVD+R ID and says "WTF?" and spits it back out.
That's why changing the booktype in the header to DVD-ROM for DVD+R
discs sometimes works. It makes the player see a disc type it
recognizes and at then it at least ATTEMPTs to play it. Most of the
time, the player is technically capable of playing DVD+R, the drive
just never tries to do it because the firmware says it doesn't know
what to do with it. Sort of like the kid that won't even try Brussel
sprouts. The biggest hurdle is getting it to try it.

Thank you all for the flood of responces to my question.
However I have found out that Panasonic players built in the last year
will not play DVD+ even though they advertise that they will play
them. I use Nero to burn and at times use a DVD duplicator to burn
both + and - and still the DVD+ have a problem. I am now only using
DVD- just to save myself the agony of redoing disks that I have sold.
I still do not understand whay certain MODERN players still gag on +.
Perhaps my question can not really be answered in full because of the
complex nature of DVD.
I used + because they burn twice as fast as -.

No, they may indeed burn twice as fast on his particular drive. Some
drives are spec'd to have different max speeds for DVD+R and DVD-R
media.
