How useful is trell for DVD encodings? Should be less noise there than from a TV/VCR source? How does digital TV broadcasting fit in here?
In my experience it increases PSNR somewhat. Of course, PSNR isn't everything, but with such small differences it's nice to have a quantifiable comparison.
I also considered using mbd=1, or is that the default when using vhq? I mean if there's a difference between the "vhq" turned on by mbd=1 and the vhq parameter, what is it? And if not, do they work well together?

As far as I know, vhq is just an alias for mbd=1. You might as well try mbd=2, though. My tests have shown it to increase psnr somewhat, again.
I don't really understand mbd=2, but I'd recommend doing some testing. it chooses the encoding which minimizes sum_of_squared_errors + number_of_bits*lambda
It might only improve psnr with 2pass encoding. no, its always better
