  Also with a compression of less than 3:1 you are not going to sample a lot
minutes.
  Sampling to raw avi at 320x240 25fps the 2 gigabyte limit (of a single
file) is reached in about 5 minutes (supposing that your HD is fast enough
to write such amount of data in such short time).
  This means that with a compression of 3:1 you can only sample about
15 minutes before the 2 gigabyte limit hits in (and what's worse: If the
sampling program does not check the 2 gigabyte limit, the file will grow
over 2GB, making it impossible to open, at least in win9x).

  With current >1GHz computers it's perfectly possible to sample for
example 640x480 25 fps to MPEG-4 (eg. DivX) in real-time (I personally do
this all the time).
