m2v, What the heck?

Hi guys,
the thing is that I downloaded this video, but it turns out to have an m2v ext.,
still, WMedia Player played it with no truble.
and it says that it is an MPEG file, so I say to my self: well, what's it gonna be,
m2v or MPEG?,
I went to do some research on the web and find that its the same.
But still, what's the thing with this file?
cus usually the mpeg's that I download are mpg,
will it play on my DivX Home Theater? I would certanly like that, cus the quality
on this video is much better that the real mpg's.

I know I almos make no sence,
but still any coment will be welcomed.


---btw: Damn, how hot is Madonna! I can't believe she's 48.
I'd still...,hum, well, you know.

m2v = MPEG-2 (SVCD)
mpg = MPEG-1 (VCD)
both will play with .mpg or .mpeg extention

Oooh!
That makes it clear man,
Thanks.
