No wonder you get problems. The journal and other data updated (e.g. last-access time stamp updates) must have piled up in the filesystem buffer. Umounting requires them to be flushed to disk, which cannto be done due to non-writability. Just use the following for mounting the mapped DVD: mount -t ext3 -o ro /dev/mapper/dvd ~/dvd That should fix things.
