thanks sam, and ryan, and mark, and doug.

it's obvious that i'm going to have to learn a little bit; there appears
to be a pretty steep learning curve, as with everything that isn't just
a matter of hitting the "do it" button on a GUI.

sam, just so i have some extra lingo, what are some other "container
formats" besides AVI?

and what's the difference between MPEG-2 and MPEG-4 which ryan
suggested?  are the "-2" and "-4" what people call "layer", as in "mpeg
layer 3"?  so is MPEG both an audio and a video encoding scheme?

it looks like this process is similar to making mp3's.  first you rip,
then you encode.  probably because, as ryan pointed out, encoding is an
expensive process.  so here is what i gather from everybody's replies:

1. it looks like i have a few choices for ripping to disk:


2. and a few choices for encoding:

   mencoder (part of mplayer distribution)

3. between ripping and encoding, ryan gave a suggestion on basic editing
   like cutting out commercials or "upcoming attractions" of movies that
   were released 5 years ago (i hate the fact that they put upcoming
   attraction on videos that i purchase).  a few is ok, but sometimes
   they really let it get out of hand).


so is this about right?

also, sometimes i see people write "DivX ;-)".  what exactly does that
smiley face mean?  and what exactly is DivX anyhow?

thanks everybody, for bringing me up to speed.
