Original commit message from CVS: Added DivX ;-) support by using the wine .dll loader. you must unzip binaries.zip from http://divx.euro.ru/binaries.zip into the win32 directory **of the source tree**. Extended and bugfixed thr riff parser to support DivX ;-) Extended the avi parser to support DivX ;-) and MPEG Layer 3. Fixed a bug in mpg123. Sound still is seriously wrong with layer 3. Fixed MPEG2 playback in gstplay. Time indication in gstplay is temporarly broken.
