I was going to suggest the following wording:


<P>There is a hack that allows AVI files to contain an Ogg Vorbis audio
  stream, but makes them incompatible with standard AVI. <B>MPlayer</B>
  supports playing these files. Seeking is also implemented but severely
  hampered by badly encoded files with confusing headers. Unfortunately the
  only encoder currently capable of creating these files, nandub, has this
  problem.</P>

<P><B>NOTE:</B> DV cameras create raw DV streams that DV grabbing utilities
convert to two different types of AVI files. The AVI will then contain either
separate audio and video streams that <B>MPlayer</B> can play or the raw DV
stream for which support is under development.</P>


but when I did a 'cvs update' to make a diff I noticed that Gabucino
was quicker and removed the whole paragraph.  Just as good I guess.
If you prefer the updated wording, apply my patch. If not, just ignore
it.

Diego
