It sounds strictly like your version of [#from_pix] is swapping the red 
and blue channels. This is surely due to my mistakes, and is certainly 
something that we tried using a PPC emulator on a MacIntel laptop, but 
accidentally appeared to work, possibly because it's not a real PPC. I 
really thought I had fixed everything at the time of GF 9.9. We need to 
find a real PPC box to test this.

It's supposed to be working with both the .mov suffix and the .avi suffix, 
but when I try to encode a .avi, it encodes it in QuickTime format, the 
same as .mov ... because the encoder doesn't really check for the file 
suffix, only [#out] checks the suffix, and [#out] doesn't really know 
about specific formats.

Apart from that, I don't have any problems at all with the encoding under 
Ubuntu, but I have not run it on PPC since 2006, and I didn't try the 
libquicktime stuff back then.

I will need more info about the crash. Do you know how to send me a 
backtrace ?
