Is there an app that can convert videos such as mpg, avi, etc… to DVD format faster? Like one that can take advantage of dual processors? It is ridiculous how slow Nero and others are.
Not really that ridiculous, it has to copy and change the output format. You probably could convert quicker, but it would reduce the quality.
Yup, would always reduce the target quality.
Even if quality remained the same, intensive linear tasks like A/V stream conversion are not going to be made much more efficient by using dual CPU processors. It can even lengthen the process due to aberrant pipeline conflicts.
An arguably better use of dual CPU might be to convert two titles at the same time, allocating separate CPUs to each task. You wouldn’t be able to do much else with your PC for a while though ;).
