K9copy error in Debian-Lenny

[charlie <ariestao@clearmail.com.au>]

I have installed Lenny and attempted to use k9copy only to have my CPU
overloaded and a crash finally. The libdvdread: CHECK_VALUE failed in
ifo_read.c:1539 last number is different just keeps going on.

It seems this has been a problem on Ubuntu - but I can't get any
information for Debian, and no fix for this problem. I may be missing
something - but what?

*** libdvdread: CHECK_VALUE failed in ifo_read.c:1539 ***
*** for info_length % sizeof(cell_adr_t) == 0 ***

libdvdread: Invalid title IFO (VTS_01_0.IFO).
libdvdread: Invalid IFO for title 4 (VTS_04_0.IFO).
libdvdread: Invalid IFO for title 4 (VTS_04_0.BUP).
KCrash: Application 'k9copy' crashing...

Any ideas would be appreciated.

Thank you,
Charlie
