Wuh...?

I have been getting components for a PowerPC-based machine over the past week or so. This morning, the DVD drive turned up (it's convenient to have DVD writers in everything, and since they're about £30 these days it's not breaking the bank getting one). This morning, an LG GSA-H10N turned up. First thing that grabbed my attention was the list of requirements (here are the ridiculous ones):

• Requires a Pentium III 700MHz or greater, recommends a Pentium IV 2.4GHz and 512MB of memory.
• Video card with 128MB of memory.
• Hard disk with at least 20GB of free space.
• OS requirements: Windows 2000/XP and DirectX 9.0 or greater.

Most of them made me think "yeah, I guess if the drive is knocked into PIO mode it'll eat CPU like a bastard" and "Sure, I bet a load of people whinge that they can't make discs when they don't have enough space to write a UDF image before writing", but really - do you need an über graphics card with that much video/texture memory and DirectX 9 just to whack 4.5GB/9GB of data onto a disc?
