3.96.1 won't do VBR heards and nogap at the same time anyway. I had them fix this (based on previous information from Peter, I think), but I think it got added after that release.

Edit: Nope. You have to use the --nogaptags flag to get it to write the headers. I forgot about that.

Reedit: Peter. Not Roger. I keep doing that, even though I've now met you both in person. At the same time. Sorry guys.
