Well happy to say I was wrong and you learn something new everyday. So you can copy DTheather with a work around. I noticed some references to using a Samsung T165, which I have, does anyone know how the exact process works (perhaps PM me)? If I can do it, I can also make a 1:1 copy. I'd like to backup all my tapes.

Does anyone have a list of the decoded tapes? Is one of them The Ring? I wanted to make a copy of that DVHS, since the tape is rumored to have the original theatrical blue color timing vs the Blu-ray's green color timing.

I believe that the D-theater tapes started at 25 GB and ran up to 50 GB and the bitrate maxed out at 28.2 but floated in the mid 20s at a constant bitrate. Alien was probably 25 GB. The back of the tapes lists a AC3, PCM and DTS soundtrack so if accurate you should have that in the TS.
