The first frame in the media starts at 0.25 sec. Chrome ignores this gap and reports a buffered range starting at 0. Firefox reports this gap and it is larger than what we will jump at the beginning. I suggest working with the encoder to make the content start at 0, or using presentationTimeOffset in the manifest.

We are working on gap jumping which will help this content, see #555.

Since this seems to be the same issue as #555, I'm going to close it as a duplicate. We'll be addressing #555 as soon as possible. Thanks!
