DC Universe has these shorts in HD on their streaming service. They aren’t well cleaned, but I’ve had some decent results with screenshots with those transfers and an HD grain plate.
DC Universe is only available in the US… Are they transferred directly from the films or they are the up-scaled and badly de-noised versions of GAIAM?
Finally, in my project I decided to use WB sound where available and I 've noticed some more differences from Bosko and the other video releases.
“At Electric Earthquake”, the music of the introduction is the right one, but it’s not synchronized correctly. It has to start almost 0,5 sec. earlier. The fact that the other versions are correct is proved from the sound effect when the letter Q of the word “Earthquake” is cracked. In the WB it isn’t connected with this sequence. From “faster than a speeding bullet” and on, it’s synchronized correctly.
At Volcano, Bulleteers and perhaps other shorts (I haven’t checked all of them yet), the music of the introduction is wrong. The first music phrase is played once and the ending of the introduction is the longer one. At the other versions, the first music phrase is played twice and the ending is shorter.
