I have emerged transcode, lame and divx4linux by the usual means. I've also tested various sets of optimization flags, they make no difference in this issue. Transcode segfaults when in the same dir as the file(s) it works on. Here's an example: [root@hiro tmp]# pwd /mnt/yt/movies/lola_rennt/tmp [root@hiro tmp]# transcode -a 0 -x vob,null -i /mnt/yt/movies//lola_rennt/vob/001 -w 1141,250,100 -b 128,0,0 -s 1.857 --a52_drc_off -V -f 25 -Y 64,8,64,8 -B 12,10,8 -R 1 -y divx4,null -o /dev/null transcode v0.6.3.20021205 (C) 2001-2002 Thomas

I'll try changing dvd::rip to not cd'ing, but I don't know if I succeed or if it helps.
Lo and behold: Changing /usr/lib/perl5/site_perl/5.8.0/Video/DVDRip/Title.pm at the lines 1790 and 2182 (removing the "cd") works for me.
This is most likely no dvd::rip or transcode bug, but a well known bug in the Divx5 codec. Quoting form: http://www.exit1.org/dvdrip/doc/faq.cipp#faq11 : This is an annoying bug in the Divx5 codec. It tries to create a file c:\trace_b.txt, which fails if you work on a vfat filesystem, because this filename is illegal under Windows. Execute the following Perl one-liner as root (thanks to Christian Marillat) to patch the codec library file (probably the location is different on your system): perl -pi -e 's|c:\\trace_b.txt|/dev/null\0\0\0\0\0|' \ /usr/lib/libdivxencore.so
I've checked this with my installation and the one-liner fix indeed works. Maybe it should be integrated into the divx4linux ebuild?
Fixed in -r2, thanks.
