Will check this then.=20

No problem. Attached.

It just uses V0+1 and A0+1. To be exact, I'm just trying to =20
concatenate two streams here. Mplayer is able to play them=20
correctly, but I failed to concat them with any other tools=20
I have. The best result produces avicat, but Mplayer still=20
chokes with=20
"Bad interleaved AVI file detected, switching to -ni mode"
and looses audio on that gap.

Here's avitype's output:

BTW: There are quite a few reasons for me to use and to look into openvip.
I'm a big fan of python programs with C[++] backends. My personal
favorite is the sip/PyQt Combo. Epecially sip4 is very promising,
being able to wrap C++ libs without generating any Python stub,=20
lazy instancing and the like.=20

Anyway, I understand your reasoning using wx, I've been there before ;-)
