OK, I searched all the web, from the surface to the deep, and still not found an MPEG2 version of EP1... or, better, there was at least a small version, around 9GB, but I guess there should be another - like the Cinemax ones - around 16/17GB... if someone is aware of its existence, please let me know.
Plus, it will be great to have a confirmation that there is an HDTV of the EP1 theatrical version - as it should have been broadcasted, following few scarces sources - while it seems there were no 1997 SE HDTV broadcast record - even if there are rumors that EP4 and EP5 were transmitted in UK, while EP6 was the 2004 version.
