Installing Lame 3.92 and Ogg 1.0 !!

AFAIK my friend what you need is Radium mp3 codec, not Lame. If you wonna make movies with Lame mp3 the best way to go is BeSweet, and you'll have to demux audio first.

Lame doesn't have to be installed. Download RazorLame (the GUI for Lame), place the Lame dll file in the RazorLame directory, point to it in the menu of RazorLame if not already done, encode from WAV to mp3 as usual, use nandub to mux audio & video.

You can set up lame to appear in VirtualDub by browsing to the ACM directory in the Lame distribution, right clicking LameACM.inf and selecting install. It will be added to VirtualDub (and other programs) as Lame MP3.
