Allison,
I don't understand exactly what you mean by "SD DV mpeg2 data". DV (aka,
MiniDV) is a different format that does not use MPEG-2.
Assuming you're just referring to interlaced content, there is no perfect
way to display interlaced material on a progressive display like a
computer monitor.
Some deinterlacing techniques include "bobbing" (meaning doubling each
line in a field) and "weaving" (meaning displaying each frame as a unit,
with separate fields woven together).
libmpeg2 does not implement any deinterlacing techniques. It _only_
performs the MPEG-2 decoding process. The display process is up to the
application that harnesses libmpeg2.
Some of the applications that can use libmpeg2, and do implement various
deinterlacing methods, include mplayer, xine, and vlc. If you want
good-looking results, you should either implement deinterlacing or use one
of those applications. libmpeg2 does not do this.
Best regards,
Keith

hi,
When I use mpeg2lib to decoder SD DV data, I can see sawtooth clear
when there is quick moving in picture.
I think it because just deinterlacing is too slow or meet some wrong. PC
I used is high performance PC, and can decoder SD DV mpeg2 data about
more than 30fps.
