A stupid question

[symonjfox]

I saw there are many versions of Virtual Dub (like Nandub, Virtual Dub Sync, Virtual Dub Mod, and others) so my question is:

Why are these programs standalone?
Or better, why don't the programmers join togeter and create a new Vdub which has all improvements made in the other versions?

I know it's a stupid question, but I'm quite annoyed that I must use one version for capture, one version for encode and another for multiplex VBR audio ... isn't it better have a new relase with all these improvements?

Yes this IS a stupid question, what do you think VirtualDubMod is all about? :p

Yes, I understood, but I wanted to say, the "orginal" Vdub.
so Why the ORIGINAL Virtual Dub doesn't have all these improvements, but I must use modified versions?

I like Vdub and other versions, I always use them.
I'm sorry, my english is awful ...
