So there isn't a real differece between DVD+R and DVD-R but the price, speed and quality of each and each blank.
I am not sure I understand your first question, at least not fully.
Some older DVD players, for example, might have trouble reading DVD+R.
DVD-R is more compatible with them.
Newer players in many cases read both -R and +R.
I did have trouble reading +R with a newer Panasonic and an older Toshiba.
Sony players are usually quick to recognize, read and then play DVD video content (such as home videos) on -R/+R media.
To answer your second question: essentially yes.
If anyone here disagrees, feel free to give XplOit more feedback.
