The original linecount values were based on input from Herbert Duerr (email attached). He ran the camera under win98 and had an analyzer (or something) that allowed him to read the regs after setting it in different modes. This was done before the camera driver worked at all - we were desperately trying to get enough of the registers right so that we'd get something decipherable. Have you tried it with the other values? If they work, then I agree it should be changed to match ovt's docs. Bret
