Can you tell me why my Disc has lines that zig-zag but yours are straight? I used the exact same settings:

Sides: 32
Segments: 1
Bottom: -500mm
Top: 500mm
Axis: Y
Center X,Y,Z: 0
Raidd X,Y,Z: 500mm

We seem to both have the same grid size even (200mm).

Check your Polygon settings under Options (hotkey 'o'), it should be Quadrangles instead of Triangles. Change that and try again! :D

Thank you. It doesn't change the existing object but creating a new one gave the desired result!

I got a lot out of this episode and enjoyed the pace. It was easy to follow.

After the 1 hour mark, the episode explores Specular Level operations and Bump Map until the end. I didn't see any noticeable results doing these operations. But I think I was using images that weren't suitable.

I had already FractalReflections.iff (the only one I had) as a texture. So for Specular Level I used the same image, resized to .5 X,Y,Z to give a different appearance. For bump map, I again used the same image scaled differenly.

I repositioned the light as done in the episode to be sure, but I think my method was just not right.

I get the general idea though and will be able to follow (and I think understand) when these are used in later episodes.

Indeed. This option is for future tool invocations. There are ways to merge existing polygons, which is a subject somewhat more advanced and will be dealt with in the future.

Specularity maps are best viewed in animations where the objects are moved in changing angles in relation to the camera/light, really. It also helps to make sure to have darker colors in your surface for the specular parts to shine through. Try maing your own specular maps, by trying say a black with white letters. Then dress it on a sphere with no other mapping. Then make the sphere red and rotate it and find an angle where the specular part will shine to the camera.
