[MPlayer-users] dvd play problem (scrambled)

[Adrian Grajdeanu]

Problem solved!

I was using the same software (same distribution, same list of packages 
at same versions) on both computers, in one this particular DVD worked, 
in the other it didn't. So what is there to do?? I suspected a hardware 
problem...

I figured I need to debug libdvdcss. I found on the net the following trick:

apollo>export DVDCSS_VERBOSE=2
and for log producing purposes:
apollo>vobcopy -O VTS_07_01.VOB

and this produces lots of useful info. among those, the fact that the 
keys for this disk were already cached in ~/.dvdcss/CHARLOTTE_DISC1-...
and that throughout the run, encoded blocks were found, for which there 
was no key. So I deleted the cached keys and retried and ... everything 
works perfectly now.

How did I end up with bad cache of keys??? Don't know. I used to have a 
different set of packages installed (and maybe no libdvdcss??) and maybe 
that was it. Maybe I started viewing and CTRL-C during the keys 
aquisition phase? As I said, have no clue. But now it is fixed. Hope 
this helps others...

And thanx to those on the list that took the time to read my verbose 
presentation of the problem and came up with suggestions.

Cheers,
A.
