I've played another DVD which, I'm 100% sure, had copy protection in the
same drive without any errors, but that was before upgrading my machine from
7.0-RELEASE to RELENG_7 on Feb 19, 2009. This DVD, however, does not play
and gives that error. Also, I have already turned the hw.ata.atapi_dma to
"0", but that didn't help either. I'm a bit skeptical about it being the
copy protection of the disc.

Any more ideas?
