Hi I'm using avidemux-2.0.36 on win 2k.

And I've noticed the following behaviour:

When avi file is opened and packed bitstream is
detected, packed bitstream is automaticaly removed.

Thats great!

But after saving such avi and playing it in bsplayer (or
MS mediaplayer), playback is yerky (I would say frames
are out of order)
On the other hand avi played well using avimux.

I think this happen because some windows players uses
also user data to determine if avi is packed or not. And
since this data was not changed together with packed
bitstream removal, avi is still played as if it is packed.

So I think the solution would be to update user data
along with removing packed bitstream.

The userdata I'm talking about looks something like this:
DivX999b000p
or
DivX999b000n

The letter "p" at the end means avi has packed bitstream
and
the letter "n" at the end means there is no packed
bitstreamm

So I believe changing letter "p" to "n" should do the trick

At least this is how it is done with MPEG4Modifier
(http://www.moitah.net) tool which also removes
packed bitstream it but is much slower.

Best regards,
Mariolino
