In the standalone player I have a "no disk in" message and in the DVD-ROM player if for example I try to play the DVD-R with mplayer, the player hangs in an "endless reading loop" with no result (I have some syslog messages but they are only revelant of a "bad medium" on FreeBSD).

I think you could add a note on the compatibility page about the need of -use-the-force-luke=dao to burn a DVD-R with a BTC 1008. I did not try with a DVD+R yet, but I assume if a DVD+RW is working without the dao mode it "should" be the same with a DVD+R. Thanks!
