Answer 1

In order to encode to WebM, you need to compile FFmpeg with libvpx support. Your FFmpeg 1.0 has this, as can be observed in the --enable-libvpx compilation flag.

FFmpeg, starting with 0.6, supports WebM:

This release features a lot of improvements that are relevant for HTML5 video. […] This release supports Google's newly released libvpx library for the VP8 codec and WEBM container.

Since you run 0.6.5, you could either recompile your existing old version with libvpx, or better yet, upgrade to a newer version that is not over two years old and probably has had hundreds of bugs fixed in the meantime. Mind you that the command line syntax has also changed quite significantly over the years.
