Thanks! With the cvs version mplayer will play back the avi file created
by mencoder.

For my next newbie question:

The resulting avi looks very pixelated (probably the wrong term ... lots
of rectangular blocks of color are apparent in the output).

So, the question is, what's happening between here:

    mplayer mf://'*jpg' -mf type=jpeg -vf scale=768:576 

... where the video looks great, and here

    mencoder mf://'*jpg' -mf type=jpeg -vf scale=768:576 -ovc lavc
    mplayer test.avi

... where the video looks blocky. And how do I fix it? I'm looking over
the encoding options, but they don't mean much to me at this point.

The jpegs are much larger than 768:576. I'm trying to scale it down to a
resonable size, e.g. suitable for the web, or a video cd.
