I do it often, in fact I just made some including one for Mission Impossible 1,2,3 and 4 which is released in cinemas this month. Made a DVD cover and Blu-ray cover and they bare being downloaded.

However I do not put on any extras information, language info etc.. and I use the previous releases as a guide to the technical details, aspect ratio, audio.

I made a set of ridiculously popular 'The Pacific' covers while they were being premièred on Sky. In the end I was asked to make something like 7 different versions of these (DVD & BD) for people who were recording them and for those who bought them when they were released I made them all with and without the extras info, they have been collectively been downloaded over 500 times, most of which was before the official release.

I'm not sure how others do these but I will never put something on the cover that I cannot know about such as subtitles, run times and language info as it causes problems later with re-edits.
There is in fact a cover on here I made, 'BBC Frozen Planet' which was made ahead of the DVD release for those people who were recording it, and it has proved very popular on other sites and has been downloaded here as well. This actually has a space for the extras information so I will be updating mine soon and sharing that as well.
