honestly, i would recommend just using XviD ( http://www.free-codecs.com/Koepi_XviD_download.htm ) instead of DivX since it works just as good but it’s FREE with no BS installed in it like DivX pretty much has.
that includes the Encoder/Decoder.
but basically if your converting DVD’s (or pretty much anything with .VOB files) into XviD format i would recommend installing that along with Gordian Knot as it makes quality XviD files that way… but it’s not super easy to use but it’s what i use and it’s not exactly hard once you know some basic’s about using it.
but basically if your converting a dvd movie into xvid format and the movie is about 2 hours long… it takes me about 2 hours to convert it on my AMD Athlon 3500+ (2.2ghz , overclocked to 2409mhz) CPU.
but basically in general some advice… if converting a 2hour+ movie into XviD format i would recommend using the “2 CD’s” (i.e. 1400MB) option… if it’s around 1 hour 30min/1hour 40min or so… then in most cases a 1 CD (i.e. 700MB) will work for it.
and in general if using the 2 CD’s option i would almost always keep the original .ac3 audio file from the dvd instead of converting it to mp3… but if your doing a 700MB route… i would convert it into anywhere from 128kbps-192kbps (usually 128kbps is probably best to keep video quality as high as possible without killing audio quality) VBR MP3 … Gordian Knot does this for you )
and as for the XviD settings… the defaults are good in most cases but in general if converting a 2hour+ movie into 1400MB i usually use the MPEG setting (sharpens image)… or if 1CD usually use the ‘h.263’ setting (softens image)
if your interested in this… then i might post more details about it. if not, then ill just leave this post as is.
p.s. my primary reason for XviD is so that i can play them back on my TV using my XBox1 console running XBMC (XBox Media Center) … as you can fit between 3 to 6 movies per DVD recordable disc this way with pretty close to dvd like quality to.
