Hi,

I've been downloading and playing some OGG format videos and it appears
that the ID_LENGTH being returned is off by about 50x for example a
video that is about 25seconds long reports an ID_LENGTH of 1234.9.

You can get the sample video here:

Here is some output that shows this.. and I have seen this on several
OGG videos. So maybe the encoder is setting it wrong, but I would like
to know if that is the case or not.
