I have a G3 PPC.  Altivec was a G4 implementation ( Velocity Engine ).  Without disabling altivec I get 'illegal instruction' failures from ffmpeg.  
As a note, I have installed the same release of ffmpeg from source, with --disable-altivec, and it works fine.  I had to have help from the 
ffmpeg user mailing list to discover this.  I would like to get my 'stuff' under MacPorts, but the install I did would not work because of 'illegal 
instructions.'  Is a patch possible?  Thanks for your help!  Best regards, Tom
