I still see that some of video classes on the O'Reilly site do not have any sequence numbers. Once downloaded, it would be up to the user to rename them in a sequence (like "01.file1.mp4", "02.fileb.mp4", "03.filen.mp4" and so on). Passing on the effort to rename files so that they appear in a sequence to the customers is really a lousy thing to do.
I can't believe it really takes this long for a company like O'Reilly to make such a minor change.
I'm sorry that I didn't respond to you promptly. Based on your earlier comments, we changed our process for new videos, so that all new videos have sequence numbers.
Unfortunately, because of the way the files are stored, there isn't a good way for us to go back to fix all videos released before the change. I'm checking in with the team again about this, but it sounds like videos released before October will not be updated.
We have a 100% satisfaction guarantee, so if you would like a refund for videos you're unsatisfied with, email firstname.lastname@example.org, and they can help you out. I hope that you'll be pleased with the way we're handling filenames for new videos.
Once again, I'm sorry for not responding to you, and I'm sorry this all has been frustrating.
