I must admit, not so keen on divx 3 myself.
But I also have to be honest, they do look good.
I could rerip them in xvid, but I don't think it will improve on quality.
Only difference would be xvid instead of divx.
Also keep in mind that it's an old series, could show you some screens from the dvd. Original isn't that great either.
You can clearly see some artifacts on them (blocks that show on high compression) in some scenes.
Overal it is still okey, far better than the Tour of Duty dvd's.
Almost started to scream when I saw the rips of those.
