First off, I checked the FAQs and I found similar topics about my question, but nothing explaining my question. Also, if this isn't the right forum, I'm sorry. I looked at 18 to 20 DVD-R topics and they were posted in 5 or 6 different forums. This forum was used the most.
Ok. Here we go. I was given a Emerson DVD/VHS Recorder. I was also given a 100 spindle of TDK PrintOn DVD-R 8x compatible 4.7GB discs.
So far they have been working great, no problems at all. I want to purchase some more, but I live in a very small town and the closest place to find them is 100 miles away. A friend of mine said she would pick some up for me, but all she could find were 16x.
According to the owner's manual, discs which can be used with this recorder are:
"DVD-R up to 16x (4x or 8x discs are recommended)"
"DVD-RW 2x and 4x (2x discs are recommended)"
So what's the difference between 8x and 16x?
Also. While I was looking online for a place to order some DVD-Rs, I seen DVD+Rs. I didn't see anything in the manual about +R. Which is best to use, -R or +R? and what is the difference?
Any help would be great.
Thank you for your time.
Sorry for the long topic, but telling the whole story works best for me.

The drive will burn at the maximum speed which it supports, It doesn't matter what the disc speed is.
Then again, some media discs give troubles on certain drives. Just make sure it's of quality or a well known brand. No cheapo "never heard of them" brands.
Given the nature of his post, I think a bit of clarification might help.
A drive is capable of burning a disc at the drive's highest rated yX "speed", however, most burn software limits the speed to whatever the disc supports (there are a few exceptions that let you tweak the speed).
For example, if you have a drive that supports burning DVD-R at up to 40X, but the disc itself has a maximum burn speed rating of 8X, then the drive is throttled to burn the disc at 8X or slower. Similarly for 16X disc.
In general, a disc capable of being "burned" at 16X will complete the job considerably faster than a disc rated at 8X (the 16X won't be precisely twice as fast as other factors enter into the "burn" process).
For technical reasons I generally advise against burning discs at their maximum rated speed, or at the maximum speed of the optical drive. This has to do with drive vibration, adaptive optics, laser control algorithms, and disc quality, disc chemistry, and more. Unless you're in a real hurry, I advise generally burning -R/+R CDs and DVDs at no more than 4X for maximum compatibility with other optical disc drives/players, and maximum data retention/reliability. If you're in a hurry, then burn at whatever within-ratings speed you desire.
Go down to the "Blank DVD Branding Data" section, see what manufacturer(s) Imation is "known" to use, and then check which quality tier the manufacturer(s) is listed.
You need to keep in mind that a disc vendor (the disc label, e.g. Imation) may change the manufacturing source of its media at any given time. What is highly rated one month may change in the next. Some brands are more consistent year-to-year from which manufacturers they get their media.
If you use a specific brand for awhile and then start having problems with it, it may be because the vendor changed who it gets the discs from. Some vendors source their media from multiple manufacturers, so it's also possible your last purchase came from a different manufacturer even though it has the same brand name label. As discussed in the article, it is possible to identify the manufacturer but only by having one of the discs in your computer so you can extract the data. It's not written on the packaging.
along with john's website info.... This utility will identify the " Real " manufacture of the disc no matter what brand label it is under. From here you can look at the different tier level it resides which will tell you if you got a good media, so-so media, or ones to stay away from. This all boils down to reliability of your burns and longevity of the disc.
remember, there are many many brands/labels of media....... but there are only few "actual" manufactures of the media.
sorry to butt in, but just searched this topic and was happy to find an intelligent set of answers. thanks much. indeed i myself will begin burning at a 4x speed to avoid problems from now on. (tho i think my burning software may already automatically adjust to an acceptable speed - but i will double check next time... )
i do video work, and sometimes a client complains that their DVD isn't playing back correctly even after i've tested the master disc on both my PC and also on a crappy $25 DVD player. (i figure if it works on a p.o.s. Magnovox, it should work anywhere...?)
also, i didn't realize how archaic my DVD-ROM drive was (Toshiba SD-R5112 at 4X), so perhaps buying spindles of 16x is overkill, LOL!
