unable to open any new DVD disks

#1 Post by JackFlack » Sat Jun 28, 2025 1:55 pm

I have been unable to open any new DVD disks with makemkv 1.18.1 [darwin(arm64-release)]. I'm on MacOS Sequoia 15.5 (apple M4 pro chip makbook). I've tried using this with three newly purchased DVDs and makemkv will open none of them. The disks are not damaged as each will play using VLC.

I get a series of errors like the ones below:

udf: udf_get_node: bad allocation extension size in udf_node
Using LibreDrive mode (v01.0 id=5FB5DFEE2318)
Using direct disc access mode
Calculated BUP offset for VTS #0 does not match one in IFO header.
Calculated BUP offset for VTS #2 does not match one in IFO header.
udf: udf_get_node: bad allocation extension size in udf_node
Calculated BUP offset for VTS #5 does not match one in IFO header.

Any solution other than moving to a different program?

Does it happen with the/a previous version?
