I use DVDFab 10 to convert HDTV files captured from Silicon Dust HDHomeRun Prime with cable card. Most are 1080i @29.97fps with 6 channel audio. A few are 720p @59.94fps with 6 channel audio. I have issues converting some files. DVDFab 10 just locks up. Any suggestions? If you need sample files, I can provide 1 or 2.
