OK, I think it would need at least firmware support to do this inside the pvrusb2 device. And I'm not sure that the information gets lost after encoding to MPEG2, doesn't it use YUV for color? If it were RGB all black pixels would of course be (0,0,0) but black YUV pixels could keep the non-zero "U" component where the hidden data is stored. At least in theory. -- Bjorn Danielsson <[EMAIL PROTECTED]> _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
