I'm partially guessing, based uponteh following: /usr/src/linux/Documentation/usb/Philips.txt mentions about palette options when insmodding the module. however, when trying w/ rgb24, insmod gives an error. grepping palette drivers/usb/pwc* displays what looks like initial load palette options (yuv420/yuv420p only), and others (in pwc-ctl (?) which I suspect is the ioctl support for this driver). > I did not believe the compressor added palettes.

I'll take a look. but, are you saying that I need to modify the source code (which I can do) ?

I'll give cvs a try. +---------------------------------------------------------------------+ You can release software that's good, software that's inexpensive, or software that's available on time.
