61c52ead7c When playing 
ftp://ftp.mplayerhq.hu/MPlayer/samples/V-codecs/QPEG/VWbig6.avi with my
decoder (should appear soon) it hadn't changed palette even there are
palette change chunks in that AVI.
Here is small patch to make it work (zero number of colors to change in
that chunk actually means to change ALL colors).

8f9298f801 * simplifying OpenDML AVI handling. 
* adding code to skip over JUNK. It turns out that video editing
     software uses junk to resize ix## chunks without actually
     scrubbing the data. That trips up our packet extraction
     code since it recognizes ix## entries as "packets". Basically
     we have to skip over JUNK chunks for exactly the same reason
     we have to skip over ix## entries.

ddaae6a9d1 * DV demuxer is now capable of decoding auxilary audio stream. So, 
everybody who still uses second streo track for dubbing can
     now export it.

   * void* -> DVDemuxContext* change (per Fabrice's suggestion).

   * -dv1394 capture now works in all modes.

7458ccbb02 * DV handling was streamlined for both muxing/demuxing and 
decoding. All muxing/demuxing functionality is now available
     in libavformat/dv.[ch].

   * dv1394.c and avidec.c were hooked up with general DV demuxer.

   * DVAUDIO is dead! Long live pcm_s16le!

   * DV audio is now always recognized -- which means we can
     now hear all those ducks quaking in pond.dv.
