Tingham: You are right - I posted a video from the Alamo using the JVC HM400 two years ago! Here is the link:
https://vimeo.com/10394295
It is interesting to compare the videos: The HM400 video now looks a bit soft with perhaps less dynamic range and is less fluid (maybe Vimeo's dealing with interlaced) compared to that of the GW77, and it was at the time one of the sharpest camcorders.
Here (again) is the GW77 Alamo video:

Shield: The RX100 is a good choice to complement the A77. Its videos will mix in well with those from the A77, as they share the same softness and moire but good dynamic range. The GW77 videos would stand out too much and make the A77 videos look soft.
If anyone wants to see the difference between what a real camcorder like the GW77 and a big sensor still camera that does video produces, I shot in the same garden and under the same lighting conditions that I took the GW77 video a video using the Sony NEX-5N, which is a large sensor camera that no one argues is inferior to the RX100 (and some have argued is superior to the A77 in low light).
Here are the links to the two videos:
First, the NEX-5N (with kit lens) video:

Then the GW77 video (same as the original post, here again for convenience):
https://vimeo.com/45606199
The NEX-5N video looks very nice, but then when you see the GW77 video you see clearly the resolution difference (and some NEX difficulty with red). I would expect the RX100 video will also be nice-looking, with good dynamic range, and its softness would only be apparent when compared with a camcorder.
