hello Qbmaster,
ivsRecode as you have reported is not free but it is not involved in exporting phase. It is used only to recode source clips to the MJPEG Codec (DPS) that allows a faster video feedback during editing phase but it is not supported with ivsEdits LE version. About support to export AVI Dvix files we will investigate if it will can be added with upcoming version 4.0. To learn more about ivsEdits LE limitations/feature you could visit this page: Compare
best regards
