Hm? You are telling that artifacts in mpeg1 and mpeg2 differ more than
in mpeg1 & mpeg4? I think that artifacts in mpeg1&2 are pretty much the
same.

If you are talking about non-interlaced (or telecined) video in half
resolution and average bitrates, there is almost no difference between
mpeg1 and 2, just that mpeg1 is more compatible. Mpeg2 kicks in on high
resolution/high bitrates or when some kind of interlacing occurs.

2 Rich: thanks for the advice, it sounds interesting...
