Check the Sonic Foundry forum right on this site. Until very recently (like a year or so ago), Vegas was owned by a company called Sonic Foundry. These are the same dudes who made Sound Forge, CD Architect, and a bunch of other audio/video applications. Sony took over and immediately released new versions of the programs (which are pretty much exactly the same as the old ones).
In any case, although the product names have changed, the Sonic Foundry forum will have what you're looking for.
