NTSC to PAL DVD conversion in Linux

I needed to convert a home-made video (well slide-show with soundtrack really) that was sent over from the USA. Attempting to play this on a PAL-only TV results in unwatchable flickering monochrome output. Based on some instructions for DVD format conversion I was able to convert the NTSC disc to PAL using the steps listed below. This was on a Fedora 10 system with the rpmfusion repos installed.

# Note: about 1.3GB of workspace was required to generate 170MB output, in this case a short slide show with sound track.
# 

yum install vobcopy mjpegtools dvdauthor
mkdir video_work
cd video_work
vobcopy -l
mkfifo stream.yuv
mplayer -ao null -noframedrop -vo yuv4mpeg VIDEONAME.vob &
cat stream.yuv|yuvfps -r25:1|yuvscaler -n p -O DVD |mpeg2enc -n p -f 8 -F 3 -o out.m2v
mplayer -ao pcm -vo null -vc dummy VIDEONAME.vob
# Note: 224000 bits per second (224kbits/sec)
ffmpeg -ab 224000 -ac 2 -ar 48000 -i audiodump.wav audiodump.ac3
mplex -f 8 -o ready-to-master.mpg out.m2v audiodump.ac3
