blodgett was having an irritating problem, could not watch dvds: preamble-y things would play, but xine etc. couldn’t access anything from title menu onwards. it would say
the source can’t be read. maybe you don’t have enough rights for this, or source doesn’t contain data
all libdvd* stuff up to date, but it would say
libdvdread: Get key for /VIDEO_TS/VTS_01_1.VOB at 0x00004436
libdvdread: Error cracking CSS key for /VIDEO_TS/VTS_01_1.VOB (0x00004436)!!
after some searching, blodgett discovered this sometimes happens with region problem. setting regions in xine settings not help at all, so blodgett install package regionset. it said
regionset version 0.1 — reads/sets region code on DVD drives
Current Region Code settings:
RPC Phase: II
type: NONE
vendor resets available: 4
user controlled changes resets available: 5
drive plays discs from region(s):, mask=0xFF
after changing region to ‘2’, it says:
regionset version 0.1 — reads/sets region code on DVD drives
Current Region Code settings:
RPC Phase: II
type: SET
vendor resets available: 4
user controlled changes resets available: 4
drive plays discs from region(s): 2, mask=0xFD
important parts: ‘type’ line now say “SET”, and last line now list region 2 instead of empty list of no regions! also number of available resets gone down, but this ok.
blodgett had to delete /home/blodgett/.dvdcss directory to remove old broken dvd informations.
and then plays! all mended.
