Disklavier

Hello, I'm doing research on a Yamaha MX100B piano that we're taking in on a trial from a store here in Phoenix. I found discs on eBay where the listing says compatible with MX100II. Is that a different model than MX100B? I understand it's not easy to format discs in modern systems and just copy files to a disc. We run Windows 10, and I also have an email into Hal Leonard about their $34.95 discs to make sure these will work. If all this so far isn't the right place to get discs, or if I can't format discs and copy in Windows10, is there another source that will make discs? I also found WebOnlyPiano.com and am waiting for their response as well.
Thanks for any input.
