Problem using transcode with xvid

I am running FC4 and severly lacking in Linux experience. I am using dvd::rip to convert my vob files to xvid. When I try to transcode, it gives me an error message; mentioning a Segmentation Fault.

dvd::rip is trying to run this command:
Code:
mkdir -m 0775 -p '/home/jimmyj/burning/EverythingIWanted/tmp' && cd /home/jimmyj/burning/EverythingIWanted/tmp && dr_exec transcode -H 10 -a 0 -x vob -i /home/jimmyj/burning/EverythingIWanted/vob/001 -w 2066,50 -b 128,0,2 -s 1.023 --a52_drc_off -I 3 -f 24,1 -M 2 -Y 12,0,12,0 -B 15,10,8 -R 1 -y xvid4,null --psu_mode --nav_seek /home/jimmyj/burning/EverythingIWanted/tmp/EverythingIWanted-001-nav.log --no_split  -o /dev/null --print_status 20 && echo DVDRIP_SUCCESS
This is the output of the command:

I have no where to begin solving this. Is it a bug or a problem with something else? And is there another program to achieve the same result?

Thank you.

Which version of transcode are you using? Dvdrip seems to be picky about this and seems to work well with transcode-0.6.14-1.1, but NOT the latest versions. Try it.

Switching to transcode 6.14 fixed my problems with segfaults.

Supposedly (per the transcode FAQ), if you are using transcode 1.0, setting the following command line parameter would help:
env LD_ASSUME_KERNEL=2.4.0 transcode ...

From what I've read, the segfaults are caused by something called exec-shield but I haven't been able to investigate or verify. If you get a chance to experiment, I would be interested in learning the results of your tests. I haven't tried it myself because I'm in the middle of a rip right now.

Where/how do you enter the value
env LD_ASSUME_KERNEL=2.4.0 transcode ?

In a terminal. You may, or may not, need to be root.
