transcoding fails

Hi,

Transcoding fails with the following error message:

Fri Sep  5 11:01:38 2008 Job 'Transcode multipass - title #2' exited with error: Job 'Transcode video - title #2, pass 1' failed with error message:
Command exits with failure code:
Command: mkdir -m 0775 -p '/home/tpapp/movies/rip/Movie/tmp' && cd /home/tpapp/movies/rip/Movie/tmp && mkdir -p /home/tpapp/movies/rip/Movie/avi/002 && execflow -n 19 transcode -H 10 -a 2 -x vob -i \/home\/tpapp\/movies\/rip\/Movie\/vob\/002\/ -w 1080,50 -A -N  -I 3 -f 24,1 -M 2 -Y 2,0,6,0 -Z 640x360 -R 1 -y xvid,null --psu_mode --nav_seek /home/tpapp/movies/rip/Movie/tmp/Movie-002-nav.log --no_split  -o /dev/null --progress_meter 2 --progress_rate 25 && echo EXECFLOW_OK

Output: 'transcode -h | more' shows a list of available command line options.
