Im too mp4 video converter 3 stalls at 99%

I am trying to convert multiple rm files to playstation 3 format using the mp4 converter. It gets to 99% each time and stalls. I have tried this with multiple files and uninstalled/reinstalled the program. Any help is welcome. I appreciate it. I purchased the program for this purpose. It worked for the 5 min conversion in the free version. The purchased version hangs at 99% for the full 25 minute video

You can setting the “Duration”, which can help you control the convert time
