[MPlayer-users] rawrgb -> Divx: -idx makes incomplete file

A little more testing and information here...
First, just as a recap: I am doing "archiving" of programs from TV. My
Mencoder command is the following:
mencoder -tv on:driver=v4l:input=1:norm=NTSC:outfmt=yuv12:width=320:height=240
-oac copy -ovc rawrgb -o "/media/Video/recorded/tv.avi"
However, when I convert to Divx, there is no index, so I can't "seek" through
the final Divx video. Also, when I play the raw video thorugh Mplayer, there
is still no index.
Now, after some testing, I have found that when using the above recording
option (for the raw video), a 5 minute recording *does* have an index. A one
hour recording does not. I am currently doing different recording times to
see at what point an index suddenly stops being created, and in fact
If this is the case, is there an option to have Mencoder record to several
different files, based on time, number of frames, etc.? If so, what is the
option. I didn't see anything in the manpage when I skimmed through it.

I took the 700MB Divx file that got created (without the index) and did the
mencoder source_file.avi -oac copy -ovc copy -o output_file.avi
but the resulting file still did not have have an index. Add the '-idx' or
'-forceidx' did not do it either.
TIA for your help and advice.
