Step 1

1) Open your video file... Click here and select Video File.
2) Check that the path is correct.
3) Click here and select the DESTINATION DIR/FILE (what file you want it to turn into and where do you want to put it). Check the box besides it afterwards.
4) Check that you've selected the BASIC preset from the sidebar (MAYBE I'll prepare a 5800XM XVID preset later when I've finished tweaking them video files to Optimum Transcoding PerfectionTM... biggrin.gif ).
5) Click here and choose MP4 file (it might also be a good idea to DO THIS before NO 3).
6) Click beside ANIMORPHIC, choose NONE. In the "Width/Height" box above it, enter "640" into the FIRST box. Leave the 2nd box empty.

Step 2

7) Click on VIDEO.
8) Click on VIDEO CODEC. Select MPEG-4 (XVID).
9) Go to AVG. BITRATE and key in 1200 (over the default 1500... This is also where you'd want to experiment to get smaller files).

Step 3

10) Click on AUDIO & SUBTITLES
11) Check the picture. You probably would have to change the MIXDOWN to stereo, and the BITRATE to 128 (also, you can experiment here, try MONO and/or a lower BITRATE).

Step 4

12) Click on START.
13) PROFIT!!!

In all actuality, converting MKV/OGM/DVDs aren't much different from the above, only with the addition of Choosing Title/Chapters (skip to the movie part, not the titles, or a specific part in the movie - it's in the Source part) for DVD; Choosing Audio Streams (again from the Audio part of the above) for MKV/OGM/DVDs; and Choosing Subtitles (see the audio part) for MKV/OGM/DVDs.
