Comment 1 for bug 1962208

The warning about it not fitting on a standard CD is a generic message we print when the image exceeds the size limit that has been declared for the image. The size limit has been raised by agreement with the Lubuntu team and the warning message will go away with the next daily build.

You are correct that the message is inaccurate, but I think it's a low priority to fix this.

Regarding choice, I guess this refers to the line 'Choose this if you are at all unsure'. I agree that this text should be removed when there is only one image option.
