Since the DVD+R format is a competing format to the DVD-R format, which is developed by the DVD Forum, it has not been approved by the DVD Forum, which claims that the DVD+R format is not an official DVD format.
The DVD+R format is divergent from the DVD-R format. Hybrid drives that can handle both, often labeled "DVD±RW", are very popular since there is not yet a single standard for recordable DVDs. There are a number of significant technical differences between the dash (or "minus") format and the plus format, though most consumers would not notice the difference. One example is the ADIP system of tracking and speed control being less susceptible to interference and error than the LPP system used by DVD-R, which makes the ADIP system more accurate at higher speeds. Also DVD+R(W) has a more robust error management system than DVD-R(W), allowing for more accurate burning to media independent of the quality of the media. Additional session linking methods are quite a bit more accurate with DVD+R(W) versus DVD-R(W), resulting in fewer damaged or unusable discs due to buffer under-run and multi-session disks with fewer PI/PO errors.
As of 2006, the market for recordable DVD technology shows little sign of settling down in favor of either the plus or dash formats, which is mostly the result of the increasing numbers of dual-format devices that can record to both formats; it has become very difficult to find new devices that can only record to one of the formats.
I hope this answered your question. The website I found this on is listed below. Good luck!

These are two slightly different formats of blank media for DVDs. There should not be a difference between the two, but as a warning, I have read in a few different places that there can be some compatability issues with DVD+R on some players. I would buy DVD-R.

DVD-R (pronounced as either DVDR, DVD "Dash" R or DVD "minus" R, depending on country) is a DVD recordable format. A DVD-R has a larger storage capacity than a CD-R, typically 4.7 GB (or 4.38 GiB) instead of 700 MB, although the capacity of the original standard developed by Pioneer was 3.95 GB (3.68 GiB). Pioneer has also developed an 8.54 GB dual layer version, which appeared on the market in 2005. A DVD-R can be written to only once, whereas a DVD-RW (DVD-rewritable) can be rewritten multiple times.
A DVD+R is a writable optical disc with 4.7 GB (4.38 GiB) of storage capacity (more precisely, 2295104 sectors of 2048 bytes each). The format was developed by a coalition of corporations, known as the DVD+RW Alliance, in mid 2002. Since the DVD+R format is a competing format to the DVD-R format, which is developed by the DVD Forum, it has not been approved by the DVD Forum, which claims that the DVD+R format is not an official DVD format.

From what I've been able to find, the DVD-R was introduced first, it's formatted to work on older DVD players (more than two years old)... As technolodgy advanced with DVD players the -R feature was upgraded to the +R. The newer DVD players will play the -R discs as well as the +R's. I personally think it's more about marketing and sales than anything else as it gives us more options to choose from depending on preference. I've heard talk that the -R's are going to be eventually phased out at some point, but that's just rumor with no fact's to back it up that I've seen. Hope that helps some.

From my research in the past they are very similar, try and find a drive that supports both. DVD-R in my experience is more common but be aware some drives will not support both formats.

disks doesn't matter however the PLAYER does matter. Some of teh older DVD players play one or the other buts most new ones can now handle both. Check your player specs to see what it can play.
