As you say, it would be better on the wiki. The problem is twofold
1/ I just don't have the time to transcribe it to wiki format - Anyone out that wants to do it, please feel free ! I'm currently being pulled back into the Xoops CMS project and I have just started a new XBMC mod to provide the facility of dvd::rip inside XBMC (cus I'm fed up of having to use a separate process to do the job. (edit: just found http://forum.xbmc.org/showthread.php?tid=52615
so I'll try and help out there instead.)
2/ Wiki is a bit of a mess at the moment (imho.) You are right, a lot of this stuff is already there, but you really have to dig around for it. But if you recall, I had to ask a lot of questions around the devs to get some stuff (you helped with this if you recall ;-) ). Wiki docs for devs really needs a good clean out/refactor. Again, I'd do it myself but for the time involved. If someone wanted to bring together what I and others have done, prune down the wiki tree and get this stuff 'in one place', that would be a great contribution to the project. If you remember, I wrote the doc in the first place 'cus I couldn't find what I needed easily in one place.
