Happy's Place Season 1 DVDs

I am having an issue making a iso back up of Happy's Place Season 1 DVDs

On Disk 1 I am getting these errors and it appears to be stuck on Title id: MENU, Current Cell: 1:6/6 Current VOBU: 32690 and not much changing except the time remaining has grown from minutes to nearly two hours and counting.

udf: udf_get_node: bad allocation extension size in udf_node

I am getting similar issues with Disk 2.

Any advice or guidance?

I have tried it with 2 different drives
LG UltraHD Blu-Ray drive and an Apple SuperDrive (DVD)

Have you tried ripping them with another backup tool yet?

I don’t know of what options exist? I’m a Mac user. Any suggestions?
