Ive been using virtualdubmod for ages now and recently ive been trying to convert some OGM files and im now getting an (error code -2)
Ive converted OGM’s before without a problem but its just happening with one series of ogm files

The specs of the OGM files :
4CC : DX50 Name : Divx 5.0
Audio Codec: Ogg_vorbis_1
Audio rate:104 kb/s (52/ch, Stereo) VBR
