Remember Me? Results 1 to 8 of 8. DVD-R 2x, 4x Differences? I keep reading here about 4x, etc. If your burner has 4x burning capabilities then it would burn a 4x disc twice as fast as a 2x disc. Generally, burning a full 1x disc takes about an hour, a 2x disc is half an hour and 4x is about 15 minutes.

If the Memorex says nothing about the speed, then it is probably 1x, but most of these can burn at 2x just fine anyway. Discs rated at 2x are kind of an oddity because it is generally believed that they are the same as 1x discs, except they are labelled so that you know that they can burn at 2x correct me if I'm wrong. You do however, need a 4x disc to burn at 4x. Something to do with the intensity of the burn or so someone else said on this site. Turn your head and cough. Does this effect which disc 1x, 2x or 4x or is it for recording the discs in less time.

The discs say on the box for general recording. In order to record at 4x you need both a 4x disc and a recorder able to record at 4x. THEN it takes less time to record. In your case however, since you have a stand alone recorder ,it will ONLY record as fast as the source. The longer the record time the lower the bitrate.

You are proberly confused with the following : Mb Megabit: 1 million bits. MB Megabyte: 1 million bytes. Manufacturers , or I should say their marketing people like to confuse the public with numbers. Since 'megabits' gives a higher number than 'megabytes' ,and they are the same letters, they often use them to confuse and distract. You are correct BUT so am I.. The time listed on a DVD box for the disks means nothing really if your using them on a computer, and probably not much on a stand alone recorder either!

I would geuss you should be able to use 1x disks as fast as you can use 2x disks. Being you are limited to TIME to watch, not size.
