:) If you had mpg321 installed, mpg123 and mpg321 were the same binary,
and the only way to run mpg123 was to run mpg123-oss. If you modified
the alternatives, then it's possible to have mpg123 be invoked with the
mpg123 symlink. But, by default, mpg123 == mpg321.

Hm. By any chance, are you using stdin piping or network streams? I've
very recently (as in: in the last couple of hours) fixed a problem which
would cause these type of seams. It was significantly more than a
single-bit error, though, but it would happen every 4096 bytes (since
that's the size of the buffer I was using).
