On mine, Firefox tried to play the clip with QuickTime, which after a
lengthy timeout period told me the file wasn't there. (??!?!)

...OK, well that's even stranger then. I haven't changed anything. :-.

BTW, just changing to vcodec=mpeg1video on my side works fine. It's in
an avi container format, but the codec is mpeg1.

Well, it's rarer than MPEG-1, obviously. I'd say you'd be hard pressed
to find many people who frequently do video conversions and can't play
either.

Works fine on my side. If you want, I can upload the result (of this
and the previous one) for you to check if it'll work on your computer.
When you do it this way, the codec is *not* mpeg. With the files I had,
it reports a codec of YV12 - or rawyv12

Congratulations. That's culture. What you just expressed right there
with *that* song is why it's valuable to watch some classic movies and
read some classic books. Other people are probably making similar
comments all the time in movies you watch and conversations you have and
you possibly don't even notice.

This is irrelevant now that you've got it working, but I'll still
defend mencoder.<G>
I was going to suggest that you post your results online and I'd see if
I could get it playing. If so, then the problem is simply a lack of
codecs on your side...

One could argue that povray.org keeps me from getting my work done...
Hmm... ;-)

...and if somebody didn't recognise this particular reference, would it
matter?
[I wouldn't exactly describe this particular song as "well known". I
know it. But that doesn't mean much. I also know a song called "How Can
I Sing Like A Girl?" :-P ]

The question is whether this somebody wants to fit in and be part of the
local culture or not.
If the answer is "I don't care", then it doesn't matter: it's a perfectly
respectable choice to remain out of the loop. But when that somebody also
expresses dismay at finding himself excluded and unable to relate to other
people in a significant way, then it does matter. One cannot refuse to fit
while still wanting to fit at the same time.
Note that it's not a true dichotomy - nobody is able to grasp every single
bit of common knowledge lying around and there are variable levels and
scopes of "fitness" anyway - but it's up to everyone to make this kind of
choice, consciously or not.

Actually it was more a question of whether you have to be able to "get"
every single individual cultural reference to understand a conversation,
but sure, you could frame it that way.

Well then, I guess what I need to do is somehow find a group of people
who actually like the same kind of things as me. [A problem that doesn't
appear to be unique to me...]

Nah, I ment that the steps are so big that there's no MPEG-style motion
blur.

Yep, nothing serious, but still visible.

Yep, this does look good, certainly the best MPEG-1 I've ever
seen...Hey, wait a minute, I just watched it again and found out why it
looks so good:
Selected video codec: [ffmpeg2] vfm: ffmpeg (FFmpeg MPEG-2)
So I re-checked:
aero@groath ~ $ file ~/Example.mpg
/home/aero/Example.mpg: MPEG sequence, v2, MP@ML progressive Y'CbCr
4:2:0 video, LD-TV 640P, 30 fps
Seems that the MPEG-header on the file I got says it's MPEG-II with 30fps.

I even saw them on the first time I watched it - my eyes are getting
cranky about those :(. I think I'll need to watch overcompressed JPEG's
and FLV's for few months to get back to reality.
