Q1: What is the difference between DVD+R and DVD-R? Is DVD+R better than DVD-R?
Answer: Pioneer produced the first DVD writer in 1997. It used the DVD-R format. The DVD-RW came later. In 1999 the DVD Forum was formed. It embraced the DVD-R format.
In the summer of 1997 Philips lead a group (included Sony and Hewlett-Packard) that split away from other disc manufacturers because of disputed over DVD writing standards. They formed the DVD+RW alliance. Since then Dell, MCC/Verbatim, Mitsubishi, Ricoh, Thomson, and Yamaha have joined the group. They developed the DVD+RW DVD writing format and later the DVD+R format which was derived from the DVD+RW format.

Q8: On the face of DVD+RW/+R media, it should have a 4.7 GB capacity. But it looks like less than 4.7 GB on a PC?
Answer:
Generally DVD calls as:
1 KB = 1000 Bytes, 1 MB = 1000 KB, 1 GB = 1000 MB
Computer calls as:
1 KB = 1024 Bytes, 1 MB = 1024 KB, 1 GB = 1024 MB
Therefore, with a PC,
4.7 GB = 4,7000,000,000 Bytes / 1,024 = 4,589,843 KB
4,589,843 KB / 1,024 = 4,482 MB
4,482 MB / 1,024 = 4,376 GB
Which is nearly equal, 4.38 GB (a capacity shown will depend on the software) Both of them has quite same capacity but each of them has
different unit, 1000 or 1024. This will lead each has this different size view.
Q9: Why there are only 4.38GB at maximum capacity instead of 4.7 GB DVD stated?
Answer:
There is a industry inconsistence. The "4.7 GB" is actually 4.7 billion bytes. But on a computer, it takes 1,048,576 bytes or 1024 Kbytes, not merely 1000 KB, to make up a full MB
