I finally found the time to test this out on linux and windows and commited it 
to cvs.

However there are still some problems:

First somehow your code generated multiple "id: [...]" entries, like this:
---snip---
id: en, index: 0
timestamp: 00:00:00:919, filepos: 000000096
timestamp: 00:00:00:919, filepos: 000000896
timestamp: 00:00:03:359, filepos: 000001096

id: en, index: 0
timestamp: 00:00:00:919, filepos: 000001896
timestamp: 00:00:00:919, filepos: 000002096
timestamp: 00:00:03:359, filepos: 000002896
timestamp: 00:00:05:480, filepos: 000003096
[...]
---snip---

I encoded chapter 4 from german r2 Star Wars EP1 dvd 1 main movie like this:
mencoder -vop scale=512:224,crop=718:436:2:70 -sws 6 -dvd 1 -alang en -sid 0 
-chapter 4-4 -lavcopts vcodec=mpeg4:vhq:v4mv:vqmin=2:vbitrate=900:vme=4 
-lameopts q=5 -o /mnt/smb1/dvdrip/menctest/swep1vobsub.avi -vobsubout 
/mnt/smb1/dvdrip/menctest/swep1vobsub -ovc lavc -oac mp3lame

At the beginning of encoding there where some duplicated frames:
---snip---
Writing AVI header...
Pos:   0.9s     22f ( 1%)  14fps Trem:   1min   9mb  A-V:-0.084 [0:119]
duplicate 1 frame(s)!!!
Pos:   1.3s     32f ( 1%)  15fps Trem:   2min  10mb  A-V:-0.084 [863:119]
duplicate 1 frame(s)!!!
Pos:   1.8s     42f ( 1%)  16fps Trem:   2min  11mb  A-V:-0.084 [811:119]
---snip---

Secondly, windows VobSub doesn't detect mencoder-generated vobsub, not 
automatically on playback nor with any of the vobsub edit tools.
These are possible causes:
- I didn't copy the IFO, as not needed by recent vobsub as I use.
- Your idx file is v3 and current are v7 which have some more fields.
- Your idx file uses unix linewraps, vobsub win uses dos linewraps.
- Your .sub file is not correctly recognized by vobsub.

As I did some experimenting, editing the idx (making it a v7 file and using 
dos linewraps etc.) and still had no luck, I think the problem is the actual 
.sub file.

Maybe I or you should ask gabest for help on this topic...
