So, what do you do with your Video

• DVD - medium of choice for Video - information on DVD Licensing
• Internet - free distribution of content/publicity/mp3 music model?
• CDROM - problems with large video files or read speed.
• Will OGG/Theora/Vorbis/Internet be the next killer app?
• Ogg Vorbis is a completely open, patent-free, professional audio encoding and streaming technology with all the benefits of Open Source.
