i'm pretty surprised there is not a preservation thread just for the streamline dubs that are not on dvd there are plenty of them.
You would'nt have to preserve the vhs/laserdisc/ordvd video either just rip and upload them as audio files if you had the equipment and nohow which I do not.
the only problems I could foresee is that the audio might not sync properly with the remastered region 1 releases that come without those streamline dubs, but there is probalbly software to fix that.
I have begged and pleaded on these forums for someone to preserve akira criterion special edition CAV laserdisc release as the audio is superior to that on the region 2 fullscreen or region 4 australian dvd's. Plus it does not suffer from pal speedup or heavy compression. (this is only a worthwhile project if someone has an ac3 rf out equiped laserdisc player of good quality and can capture the full bitrate pcm off the discs) otherwise just get the foreign release rip the audio and fix it for ntsc consumption or bear with the speed up problems and no nothing.
The greencapt project has unofficially been abandoned any takers?
Some of the streamline dubs are included in the ghibli laserdisc box set I own I just do not have the equipment to capture the audio. Plus they are only monoural so if you could find them on any region 2 dvd in stereo that is your best bet.
How awful is the english dub on warriors of the wind is it even worth preserving?
