I sent my September 1995 copy of the FOCUS VHS tape to nettapes.com, after
completing the online payment. Then I converted the CD I got back:

ffmpeg -i /mnt/cdrom/video_ts/vts_01_1.vob \
 -b 400k \
 -ar 24000 \
 -ac 1 \
 -ss 00:00:31.00 \
 -t 00:01:43.60 \
 -s 640x480 \
 ~/downloads/focus.mpg

That took several hours of trial-and-error to get the right start time and
duration. Then I recorded an intro on my Optio W10, saved it to my disk, and
did the same trial-and-error until I got just the part I wanted:

ffmpeg -i /mnt/m/optio_w10/108_0429/IMGP1101.MOV \
 -b 400k \
 -ar 24000 \
 -ss 00:00:55.00 \
 -t 00:00:22.00 \
 ~/downloads/focus_intro.mpg

Now joining the two:

cat ~/downloads/focus_intro.mpg \
 ~/downloads/focus.mpg \
 > ~/downloads/video_resume.mpg

Then converted to WMV format... perhaps not necessary, but uploading to YouTube
is so slow, I wanted to get it right the first time:

ffmpeg -i ~/downloads/video_resume.mpg ~/downloads/video_resume.wmv
