It seems as it was too good to be true….
It seems as are there some problems with the RC2 DVDs.
There are a few episodes with a speed/pitched up (?) voice of Al.
Here are two samples, one sounds “normal” the other one like a speed up verision (but it was not modified)
It seems as there was a problem while converting the videos from the NTSC to PAL standard.
There is a speedup from about 4%.
