When the Warner Archive says a title has been "Re-mastered", that means a new video master of that film had been created (usually for TCM or another cable network). This new film to video transfer would be superior to the previous video master that The Warner Archive had used for their MOD DVD-Rs of that title. So The Warner Archive is telling their fans that they should buy the title again, because now it looks better. On a few rare occasions, The Warner Archive only had access to "Pan & Scan" TV video tapes of some widescreen movies. These are being replaced by new 16x9 transfers as the Cable Networks request that format. The Warner Archive Thread here at the Home Theater Forum has been discussing this. http://www.hometheat...-the-films/3810
Actually, the converse of what is stated above is the actuality, as I understand it. Warner Archives has NEVER released a 'pan and scan' title to my knowledge. While it is accurate to say that their initial releases years ago used 'existing sources', that has been less and less the case in recent years. It is fairly well established that they began to do their own remastering and have done so for hundreds of features and several TV series in the last few years. They are the ones remastering films in 16x9 when nothing else is available, while TV airings often continue to be from an older source. Of course remastering and restoration are two totally different issues (and restoration is really what is relevant to this thread about classic animation), although Warner Archives has indicated some photochemical restorations were sourced for several of the new remastered titles that they have issued. Again, relating to feature films, just to clarify.
