Perhaps ffmpeg/mencoder (available on either platform)

to split:

ffmpeg -sameq -ss [start_seconds] -t [duration_seconds] -i [input_file] [outputfile]

ffmpeg -sameq -ss 2 -t 4 -i input.avi video1.avi
ffmpeg -sameq -ss 8 -t 2 -i input.avi video2.avi

to merge:

mencoder -ovc copy -oac copy video1.avi video2.avi -o output.avi

does it work on divx encoded videos? let me check.. – iceman Nov 26 '09 at 20:20
small corrections ; -t duration' : Restrict the transcoded/captured video sequence to the duration specified in seconds. hh:mm:ss[.xxx] syntax is also supported. -ss position' : Seek to given time position in seconds. hh:mm:ss[.xxx] syntax is also supported. Itried this and it worked but the video and the audio are time shifted and also there's a big difference in the original and output quality.The output's very degraded. DivX is a variant of MPEG4 hence we can ffmpeg as it can produce MPEG4 on its own – iceman Nov 26 '09 at 21:03
I left out the hh:mm:ss given the context of your answer. I admit, I tried this in a ssh connection to home. Didn't verify the quality. Perhaps try doing it all w/ mencoder? – basszero Nov 28 '09 at 14:35

To split the video there's a hand command line tool called jumptheshark.
