Three methods I've found. The simplest one seems to be to use VirtualDub,
http://neuron2.net/delogo132/delogo.html
http://compression.ru/video/logo_removal/index_en.html

you could also attempt to do it manually with mplayer's delogo or remove
logo, but it's fiddly.
delogo[=x:y:w:h:t]
remove-logo=/path/to/logo_bitmap_file_name.pgm


The most effective way is probably too much of an investment for most -
use a custom designed FPGA

Note that the person behind that is not too far away.
