[MPlayer-users] Confused about deinterlacing and scaling

[*]

Hello, I'm about to spend 14+ days encoding some DVDs of television
shows and it would be *fantastic* if someone could glance at my
options and point out anything wrong (from past history I'm positive
I must be doing at least a couple things wrong).

In particular I'm confused about the pp to use for deinterlacing.
It sounds like pp=lb is best in theory but I have to say that pp=ci
looks a lot less blurry.

Also I'm not clear on whether (or how) to scale after deinterlacing
and cropping.

Anyway here are some relevant lines from the mplayer header:

    VIDEO:  MPEG2  720x480  (aspect 2)  29.970 fps  9800.0 kbps
    Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
    VO: [xv] 720x480 => 720x540 Planar YV12

Maybe the 720x540 means it was originally PAL TV?
And here are the full 2-pass commands I was planning on using:

    mencoder -aid 128 -oac copy -ovc lavc
    -lavcopts mbd=2:mv0:trell:cbp:precmp=2:cmp=2:subcmp=2:
              vmax_b_frames=1:predia=2:dia=2:preme=2:vme=4:
              v4mv:vbitrate=868:vpass=1
    -vf pp=lb,crop=712:480:4:0,scale=640:480,hqdn3d
    -ofps 29.970 -o /dev/null movie.vob

    mencoder -aid 128 -oac copy -ovc lavc
    -lavcopts mbd=2:mv0:trell:cbp:precmp=2:cmp=2:subcmp=2:
              vmax_b_frames=1:predia=2:dia=2:preme=2:vme=4:
              v4mv:vbitrate=868:vpass=2
    -vf pp=lb,crop=712:480:4:0,scale=640:480,hqdn3d
    -ofps 29.970 -o movie.avi movie.vob

Thanks!
