Small step for a man...giant leap....
Added ffdshow processor in filters and...surprise !!!
But still
, audio and video are not synchronized, file skips every 3 seconds.
LE: Installed Haali. Confirmed, Haali doesn't detect the audio stream.
LE2: If the files are home made, the program you use to create them, must have audio and video compresion options. This file have 6,6 MB, from which 30% is video stream, 70 % is audio, as it uncompressed PCM. Maybe you can find better settings for the encoders (MPEG4 instead of MPEG2 for video, AAC for audio) that will also reflect in file size. I have converted it in MPEG4 / MP3 and it's 1,1 MB, 6 times smaller (948 kb - 86% video and 167 kb - 14% audio).
