serious DVD problem (never come across this one before)

nadir

ok I just ordered 2 dvds from japan.
ive tried playing them on 2 dvd drives an lg and pioneer, on linux and windows.
Both fail

mplayer gives the usual error

============ Sorry, this file format is not recognized/supported =============
=== If this file is an AVI, ASF or MPEG stream, please contact the author! ===

furthermore attempts to make isos with mkisofs or copy with
dd if=/dev/hdc
or
mkisofs -dvd-video /mnt/dvd/ > /iso

all yield

0ÃhÑ£Fmxtermxtermdd: reading `/dev/hdc': Input/output error
1152+0 records in
1152+0 records out

im totally confused, acidrip and dvdrip also fail , infact crash , and i need to reset the jumpers on the lg dvd drive for it to be detected at boot. heh

like i was saying windows is the same, powerdvd fails, and so does the ati player, ive also checked the region info, the lg one has 4 changes left, although i think its unlocked cause ive played 100's of dvds (most japanese on it). And the pioneer one reports as unlocked.

so anyone have a clue? do i just need a new dvd player, are there some dvds that just dont work on computers, you got to have a tv player? if so that sucks. anyway, thax for your time, i hope somone knows somthing about this

Have you tried these in a set-top player? Maybe they're just buggered.

try mplayer most asian dvds i bought were actually VCDs ina weird format but mplayer either played them or found the format.

not Media player 9/10 but the older one type "mplayer" into run box.

Media player classic? Seems to play just about everything.

Solved.
ok well im not exactly sure what went wrong, but i re emerged libdvdcss (so it was an encryption prob), and then installed dvdbackup. This is a nice commandline ripping utility, and it worked straight off for both dvds. v. strange that it i couldn't play them before ripping, and even more strange that dvdrip and acid rip couldnt rip em, even though i have ripped a whole load of dvds on both of those without any encryption problems.
and now im just after encoding both dvds on the wrong framerate, god damn you ntsc
and way thanks guys for yer time,

Japanese dvds are region 2 aswell, just NTSC not PAL.
