I just sent a question to Brad's tumblr about the bombcast. For some reason, the bombcast always displays episode lengths in seconds only and the file size is always incorrect, usually something between 9 to 11 kilobytes. Apparently it's because you have to manually (or automatically) include those numbers to the RSS metadata or something. I hope he reads it but I might try contacting someone else from GB. It's just a bit if a bother not having a good gague on how long a episode is in my podcast app all until I play it.
This is what I'm talking about:
3600s is 1h, it's not that hard!
Just kidding of course, but it's working for me. What player do you use?
edit: This is how it looks here with Pocketcasts:
