MakeMKV v1.17.8 ripping very slow with HDD based mkv's

[I-Like-Movies]

I'm seeing the same issue with 1.8.1 registered. I'm using a file on one SSD and making a different version (ripping out audio/captioning tracks) on another. The rate is hovering in the 500-900k range. Since I've never had this issue before I'm wondering if something in windows 11 changed or if its a problem with the source file... Looking at task manager MakeMKV is using 10-20% of the cpu and less than 400mb of ram. HD usage is under .1MBs. Other than a web browser nothing else is running so the system is just idling
