hi, in version 3.1.0.24, when you compile the modified script, there's an error about the following [Registry] entry Root: HKCU; Subkey: "Software\VSO\ConvertXToDVD\3.0\settings"; ValueName: "TvFmt_Video_Standard"; ValueType: String; ValueData: "{code:GetVideoStandard}"; Flags: uninsdeletevalue saying : Required function or procedure 'GetVideoStandard' not found so I changed ValueData from "{code:GetVideoStandard}" to "vs_automatic" (stands for : "My devices can handle both formats" now, compiling the source script is OK just run "your_output.exe /verysilent" and that's it !
