This information has been created to help those customers who have been directed to this article via support.  If you haven’t but are experiencing troubles with selecting DVD titles, please contact support.  You may be directed to this article if you have contacted support regarding an issue with the default title being selected for copying a particular DVD. Increasingly more DVDs are intentionally being created with various types of bad data to make their DVDs difficult to copy. 123 Copy DVD offers a true Clone Mode that will make a perfect copy of any DVD disc that is in a good physical, and readable condition.

Whether you want to copy the main movie title to another DVD disc or convert that title to another format for playback on the PC or another device, you need to know which title is appropriate to select. We have analyzed thousands of discs to ensure that these DVDs select the proper title automatically. There are more movies being made every day; if you have a title you would like to copy before we’ve had a chance to analyze the disc we’d be happy to help you determine which title to select. For this we will need a couple pieces of information from the disc to be able to assist you:
  • The log file from your 123 Copy DVD program
  • The title number that plays when you’re watching the movie off of the DVD; many PC playback programs will be able to tell you.
In the following example we will be working with the free media playback program called “Media Player Classic Home Cinema” which you can download and install here:

Recommended brands of blank media

We recommend avoiding bulk blank media and store branded media as they are often poor quality and will fail during a burn. Brands that have worked well for burning discs include: RiData, Sony, TDK, Ritek G04, Verbatim Data Life, Verbatim DataLife plus, Taiyo Yuden and Mitsubishi. Media advertised as “Advanced Metal AZO” are generally good quality due to the high grade dyes used.
