Thank you for the advice. I hadn't considered Drives & Devices as a place to look for an editing option.
While this is a way to find the missing button, it seems like the Rip options could be more consistently displayed when ripping. For instance, MC could always offer the option to Edit Disk Information, even if YADB succeeds, since it fairly often pulls up wrong track data. Sometimes it works as desired. For instance, I just put in a CD to rip, MC found YADB data, AND showed me the Edit Disk Info button. In fact, it has done this for the past 8 CDs, AND waited for me to click the Rip button. And sometimes it gives me the button when YADB fails.
What's puzzling is the times when it all behaves differently, and I don't see any reason. Sometimes,whether YADB lookup fails or succeeds, I don't see the Edit button, and worse (in my situation) sometimes MC starts ripping without giving me a chance to add the track info.
In my MC, "Enable Auto-Rip Mode" is NOT checked. Yet most of the time, when I put in a CD, without clicking ANYTHING, MC looks it up in YADB, and if found, MC immediately starts ripping. Nice for some, but I prefer to review the tracks list, then start ripping manually. Maybe I'm doing something wrong, but what?
Suggestion: Also provide Edit Disc Information as a menu option, perhaps under Library Tools or Rip Disc -- and/or as a right-click option when a disc is detected. I'd like to see every MC capability in the menu system, even when also available elsewhere at times, because the main menu system should be the one place to find an action or mode no matter what else is going on. If a menu option is not applicable or useable at a given point, disable it but not hide it, so at least the user knows where to find it at the correct time.
