XviD
I was told that it XviD is better than DivX, just haven't got round to trying it. Today I am off work with a painful sinus, awful headache, hacking cough, and that lovely dizzy feeling you get with such things.
With this spare time of laying in bed making whimpering noises I set my computer off doing my first ever XviD rip. Currently I would put a standard TV episode into ±350MB. I have pulled of the same but in 170MB. Audio in MP3 96Kbps.
Highly impressive, now I just need something to rip...
XviD is open source, which can be downloaded and compiled with Visual Studio (etc) from: http://www.xvid.org/ or if you don't have a compiler, then you can download binaries from: http://www.koepi.org/
