I would encourage you to use random serial numbers, as intended, also,
as any downstream consumers of your files will face limitations similar
to the ones you are facing if they want to do anything more with them.
But before you go too far down the route of changing the serial numbers,
can you tell us what software is producing Oggs with a hard-coded serial
number to begin with?

Please see this screenshot https://giphy.com/gifs/9AIe7ksYBwiYQoLVv9/fullscreen with serials 11111111 and 22222222- it will be correct approach? And can you please say me from what region I need to calculate crc32? And also as we can see on the screenshot above - changed two groups of numbers beside the serials - what is that? Thank you very much for help.
