There are countless faqs and guides on the net concerning basic questions,
for example at http://go.to/doom9 faq sections (there are guides only for
windows software).

I wouldn't go over 50 minutes on an 80min CD but that's only my preference
:) A 80min cd can hold a ~800MB image and the length is controlled by the
video and audio bitrates. For "best" quality I recommend 2500k max VBR
(use the average bitrate to control the size) for video and 224k for audio.

Any encoder capable of creating an mpeg2 file should be able to open one
and use it as source.
