I'm using mc 4.7.4 with cdrtools 3.00 and have similar parsing errors,
but not UTF error. This happens only on some ISO files.

(There are also some files with .iso filename but are not valid ISO
format according to isoinfo. For example I have an ISO downloaded from
Microsoft that isoinfo cannot recognize.)

These 2 linux distro ISO's have different results.

openSUSE-11.2-DVD-x86_64.iso is displayed properly, here are the first
few rows from isoinfo -l -i:

Sabayon_Linux_5.2_amd64_K.iso is not, MC displays parsing errors, but
it looks similar in isoinfo:

The first parsing error is displayed for every line starting with the
first file (.)
