UPDATE #5
I am still researching and testing this new find of mine
I just wanted to let everyone know, that again, I found a way to use:
* VirtualDUB (vdub) and,
* AVIsynth
under MEncoder !!
Now, you can encode w/ mencoder using your favorite scripts or vdub. But
I must continue debuging first, before I give good steps to follow. I'm only
having one issue with it, and I'm working on it now. The issue is that:
* color is reduced to 2 or 4 (ie, blue and red, IOW.. i't not 16m colors, more
...like shades of gray w/ a few odd colors)
* video source is upside-down

and
So far, I got it working, but I'm not too sure that the method that I using is
the appropriate one to use, but never-the-less, it's working.
Also, one more thing about my latest findings..

You still can not encoder vdub files (*.vdr) directly into mencoder. You have
to frameserve them into AVIsynth, but hay, you have BOTH worlds

.
.
I haven't tested weather AVIsynth "alone" will work yet. I'm still debuggin
the above out
testing.. testing..
Cheers everyone, I'm really excited, because I've done a handful of dvd
rips and encoded to VFAPI and used my prefered methods of feeding my
source files for encoding. I am happy we (I that is) have another encoder
engine to work with, and so far, I really like the quality (as far as virtually
zerio blocks)
Well, let me get back to testing and debugging and, oh yes.. my spagetti
and soda (on the stove)
Cheers gain all,
