I was afraid you were going to say that. Yes, I can do that for you. I do know that there were some channles that i felt were cross-hatched with the old driver too but I am not sure if it is the same ones. I think channel 45 was a channel that I and several others noticed with the old driver that was particularly bad. This channel seems to be ok now with the new driver.
It will probably take me a few days to go through all the channels with both drivers, but I will try to make a detailed description of my findings.
Thanks again,
Doug

Hi Doug,
Thanks for testing. What I like to know is if the channels with
cross-hatching are also the channels that look good *without* this
patch. In other words, are bad channels now OK and formerly good
channels now bad?
