There's no doubt whatsoever that the voices and music are at a higher pitch in the recent TCM broadcasts of Singin' in the Rain. I'm not asking whether or not it's happening, I'm asking why.
I have a VHS tape on which I record my favorite musical numbers, one after another. I recorded the "All I do is Dream of You" and "Singin' in the Rain" numbers from the recent 1/23/05 broadcast. I then compared the sound to a 4-year-old TCM tape of Singin'. The difference is immediately obvious. This didn't surprise me, since all 4 of the most recent "Singin'" broadcasts I've seen have had the same problem.
Apparently, the same problem has afflicted the recent 2-disc "a Room with a View". The voices and music are a semi-tone too high.
A few people to whom I sent an e-mail about the upcoming broadcast of "Singin'" told me they had to turn off the movie because it was "annoying".
Since Singin' in the Rain is one of the top 10 films in TCM's library, I hope the problem is corrected. You're running a bad print lately.
