I'm using these settings now
  DivX 6 AVI-file. 8. 4 Codec.
  But I always record with which they should get audio / visual lag, the audio is ahead of the source. What video settings should be used to get the perfect sound / visual line up?

I need a good topic would not be too general or common. No one should think of him so easily, it is best if it is something like an audiovisual presentation, a visual presentation, a fixed model or a model of work (not experiments), a pair of thirteen year old can handle themselves . It would be nice, but its another simple issue, even in "organic chemistry" or "Medicinal Chemistry".

The restaurant should serve healthy foods, such as oil, free food, grilled food without added sugar cakes. Necessary audio-visual system. P600 per head budget

I do not use Singlish.
  I socialize with Westerners.
  If videos / books, any recommendations?
  Audio / visual to help recommend?
  I am unable to travel to U.S. for a long time but just be there for 2 weeks next month.

In French class who are obliged to make a speech and presentation of audio / video. I'm doing mine on Mount Fuji, and need an impressive audio / visual presentation. It may be a sign, but I need a good layout, so it is not boring.
  Thanks
