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.
