I just applied the update as well and went through each channel on  
both tuners.

The image quality on both tuners is now good and at least match each  
other.  However, I will second Lonnie's comment about the cross- 
hatching of channels.

I found that most  channels are not affected.  On those channels that  
are affected, some channels are worse than others. Channel 39  
(313.250 MHz) seems a lot worse than all of them.  On that channel,  
instead of just cross hatch-lines, it looks more like flickering  
cross hatch lines.  A little more annoying.

But back on the good note, both tuners are now at least watchable and  
recordable.  Thank you for your hard work and time Hans to get this  
far.  Let me know if you would like a more detailed list of exactly  
which channels I am seeing the cross-hatching and if you want any  
video samples.

Thank you,

Doug
