...pidip has [pdp_ieee1394] for fw cameras (although come to think of  
it, it's basically the same code as gem's [pix_video], which can also  
use usb cameras):  however I caution against it, because it tries to  
run the quicktime sequence grabber's idle function in a seperate  
thread, which is a no-no, and causes strange cpu surges if you try to  
pause or stop the capture...hopefully we can figure out someway  
around this in the future...

...otoh, I always use Gem's [pix_video] into [pix_2pdp], which works  
very nicely (color conversion is altivec'ed, too)...you can also  
bring it back to gem for display on a geo with [pdp2gem]...both of  
these objects are in pd-extended, along with help files...
