hey chris,
you need to know a bit more about DVD-specs to do DVD-authoring.
DVD-spec is a max. data-rate about 10.08MBit/s for all assets (video/audio/subtitles).
a DVD-/+R could only have approx. 8-8.5MBit/s.
if you have a 4-5min film I would advice to use 7.8MBit/s CBR and 192kbit/s AC-3 dolby audio.
cheers
danny
PS: yes – the website is down – old application, old company, I just keept it and put it in my download-area, so newbabies will have an easy to use butbiteging-application. 🙂
