The first batch of pre-ordered GreenAntz v2.3 will have arrived for most, or be arriving soon.
CX456 has pointed out that I made an error with the coloured RCA Y-Pb-Pr output. I have got two of the coloured tabs back-to-front, such that Y (green) and Pr (red) are swapped.

AFAIK this has affected the entire first batch. My apologies

I feel devastated of course. Even so, this is a purely cosmetic error. It does not affect the normal operation of the GreenAntz at all.
How did this happen? The triple RGB RCA gang comes with the colours like that, I forgot to swap them around. Why didn't I notice a "obvious" thing like that? Probably because I am red-green colour-blind, which I have mentioned before. Not exactly "blind", but this is the kind of thing I might not notice unless I look specifically & closely. It didn't become apparent during testing, as has no practical affect.
In other news, I have used steel screws with these enclosures. I wanted to use transparent nylon screws here but they have slightly taller heads, and the inset for the head is not large enough. The nylon screws stick out by about 0.5mm. So I used steel instead, smaller head. A warning though, If you are going to open the enclosures up, that
it is easy to accidentally strip the plastic thread when re-tightening with steel screws. To avoid this, stop screwing as soon as the screw head is fully inset.
Please let us know how it goes in your setup, I hope all is well. Apologies again about the red/green mixup.
