Hi Chris, I don't know how much practical help it will be but look at <a href="http://en.wikipedia.org/wiki/MPEG-4">http://en.wikipedia.org/wiki/MPEG-4</a> for some MPEG-4 background. For ogg: <a href="http://en.wikipedia.org/wiki/Ogg">http://en.wikipedia.org/wiki/Ogg</a> for AVI: <a href="http://en.wikipedia.org/wiki/Audio_Video_Interleave">http://en.wikipedia.org/wiki/Audio_Video_Interleave</a> . As you can see , none of these is a simple, uniform format, hence your difficulty in rendering these to a DVD. This leads to further questions. Where did you get the files you want to burn? Do they come from your camera/ camcorder? Downloaded from the web? In my very limited experience Divx movies, which usually have an avi extension, that can be played on a computer, phone or tablet will usually burn as data files. Several will fit on one DVD. A minority of DVD/ blu-Ray players will play the result and the quality can be as good as a commercial DVD, but sometimes not nearly as good. The standard DVD format consists of a number of .vob, .ifo and other files in a folder named video_ts; there is also an audio_ts folder, usually empty, apparently an abandoned part of the original standard retained for compatibility purposes. In spite of the scary FBI warnings DVD's can be copied for archival backup purposes fairly easily - but you do need to defeat the copy protection, which is illegal in some countries. "You shouldn't do this" ;- ( To create a standard DVD from home movies you require an authoring programme that supports the format your camera produces. I've never done this, but others have. There is free software available, I think in the repositories. While ogg is an open source standard that can be used for encoding many audio and/or video files I've only used it for audio. If it plays on an appropriate software player you just burn it or them as data files and they should play on any hardware player designed to support ogg audio. Not many do. This is hardly a satisfactory answer to your question but it should point you to some further areas you need to research. It is not a simple matter: there are many side issues you need to consider. This is not Kubuntu or Linux's fault, its just the way the standards are evolving. As you can see, "mpeg-4", "avi" and "ogg" are not sufficient to define a file you may want to work with. If you have a more sharply focused question about all the specific sub-formats that define your file then ask away. Probably someone has "been there, done that" and can help you. Ice shared all I know, which isn't much. Good luck and don't give up! As a colleague of mine told me: "Linux is not an operating system, its a way of life!"
