AutoGK is your best bet, it's about the best thing for new users. And the preview on it is only for video, and the audio is usually 128-bit VBR MP3. And if you couldn't play the video back, get Media Player Classic and the latest XviD/DivX binaries. (Look on koepi.org for XviD).
EDIT: Try looking for guides and such on doom9.org
