Alldj DVD to iPod Ripper

Why do I use Alldj DVD to iPod Converter converters generation iPod documents I painted above the iPod occasionally stop?I would like to ask how to solve?Does the conversion time for video bitrate is too high numerical when players are unable to deal with?

Why do you use Alldj DVD to iPod Converter?
You may try to use other good convert software.
I use Daniusoft DVD to iPod Converter to convert any DVD(protected DVDs) to iPod which could convert in a good quality without any problem.
