Actually, I think it is outstanding. The tab in "Options" is easy to find and the settings are self-explanatory. I like the check box to select whether you want to select a device or be prompted. I honestly can't think of a better way. The program correctly found my 2 burners (a Plextor 4824A and a Sony DRU500A).
One miniscule point ... after installation, the "Run Settings" is "optionnal". Should be "optional".
I've found the program to be a perfect companion to DVD2one.
