[MPlayer-users] Broken avi file: "AVI: Missing video stream!?" video works, no audio though

[Da Rock]

Sorry guys - I solved this myself.

I don't know why I didn't think of this before, or perhaps I was waiting
for a reminder... anyway I ended up using -tsprobe and -forceidx.
-forceidx didn't do much, but I had to set the -tsprobe too some stupid
amount (8192000) and hey! it suddenly found an audio stream.

The MV and AC errors have disappeared so far too (probably thanks to the
-forceidx).

Thanks for your patience guys.
