Some tests combinations. I believe Dan's tests want a DVD, whereas mcicda expects audio CD-ROMs. Either you play disk jockey while running the tests, or some tests will be skipped. Note that mcicda will skip some tests unless you use a mixed audio+data CD-ROM. Few people have those. An audio only CD-ROM will not run all tests. The mcicda testsuite is known to skip correctly when no disk or a DVD is inserted. Anything else is a regression. Regards, Jörg Höhle
