LIBMKV_TRACE: Exception: Error in p->FetchFrames(2,true)

[MRD90]

Error occurs in one of the Powerpuff Girls Complete Series DVDs. Log is attached. Odd thing is it's able to clone the disc just fine, and the exact same error happens when running the mounted ISO with Daemon Tools, so I don't think the problem is with the disc. The log is from a mounted ISO run, not with raw disc.
