Hi, you can only specify the resolution, and mpeg2 or h.264 encoding in 'Create Disc'.
However, if you produce a file in 'Produce' with your required settings, copy this file to the timeline, and then in 'Create Disc' match the resolution and encoding settings to the file, PD8 will create your disc using SVRT, without re-encoding the entire project again.
Hope that helps!
