If this is the case, then I'm unaware of it with LOTM. The source that this project is based on is a "cable" version, as it's sourced from a SKY-HD broadcast in Europe, but it's actually the "theatrical cut." there may be a TV edit (from when the show made it to broadcast TV in the late 90s) but I doubt that it will have any extra footage. However, you never know what rare recording might be floating around out there in the world...
On note of project: I am creating the BD-50 with multiAVCHD as "we speak" and will be posting results and release info within next few hours ;o)
