I need to convert DVD file formats (VOB) to flash formats FLV, AVI, and/or MP4 but the most import thing for me would be the file size as I would like to keep it small as much as possible with reasonably good video quality.
I have already purchased ImTOO FLV Converter V5.2 but I am not very happy with it as it generates really large files.
Looking for suggestions for any other tool (paid or free), any idea or recommendations?
