One must understand that Jon's dislike of the Process Text Group and their line of ABC Amber products is well known and long standing.
I have used their products -- both the free ones like the Sony Converter and the purchased converters -- for many years and they have saved me many times in their format conversion. They have saved many, many hours of my time.
I have found that Yernar is responsive and concerned about the quality and usability of his tools. I am a client and am not part of Process Text Group.
