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.
