According to the information that I can find, this is caused because of an
impossible condition. The cell's block mode is angle but the block type
is normal. Since a cell w/ a block mode of angle cannot have a block
type of normal the VM asserts. This seems hardline, but still correct. I imagine
that so few  DVDs have multi-angle features that this hardly ever
comes up. The title that the original reporter is trying is known to have
additional copy protection beyond CSS. So this might be a factor.

We could modify the VM, but I don't know if it is worth it w/out more
information. Is it possible to get the original poster to try the
attached patch.
