expecting the quality of the picture to be reduced when I played it back but
when I watched it back I didn't notice any real reduction in quality at all.
Is this usual and does picture quality only visibly deteriorate when you go
to 3 hours or more?

The number of pixels is still the same (full resolution) in M2+.
The bit rate is reduced so how much difference there is depends on the
picture content with respect to details, motion and noise.
It is still a descent bit rate but depending on the the content and
what type of TV-display you use it will be more or less visible.
I am of the opinion, but I haven't proved it, that TV-displays that do
image processing (read upscaling etc with Pixel Plus) is somewhat more
sensitive to the MPEG artefacts than the human brain when displayed
directly with an analogue CRT.
And of cource a large screen = big field of view reveils more of it.
I also use M2 as my standard quality.
