In short, are you a human being?
Help is at hand, from a chap named Harmy. This colossus of a man has created a "despecialized" edition - basically an upscaling with all the new additions taken out. You can find the iso files here.
Actually playing them is a bit of a trick. The first (platform non-specific) tip is:
Make sure your files are not corrupted.
Seriously. That cost me a couple of evenings.
* mount the iso as a drive using daemon tools
* download vlc - I have this running with version 2.1
* in vlc do media -> open file -> select your virtual drive -> bdmv -> stream -> m2ts file
* mount the drive thus:
sudo mount -o loop -t udf $path_to_iso/ANH.ISO $mountpoint* download vlc or pull it from a repository (package name vlc in ubuntu)
* in vlc do media -> open file -> mountpoint -> bdmv -> stream -> m2ts file
Suddenly you're back in the past, watching Star Wars version awesome.
