This is equal to -vop pp=de - use default pp.

It's no use by some reason... It acts just like -vop pp.

don't use -de ;)

passing random strings to pp results in turning off pp at all :(

same here. pp library found error in your request and pp was disabled.

It's deactivated when you don't use -vop pp at all or use
-vop pp=smth1/smth2/etc (like -vop pp=lb). It is activated when you use
just "-vop pp" or -vop pp=smth1/smth2/etc and there is "de" somewhere in
options (like -vop pp=de/lb). Also, you can exclude some filters from
default pp (like -vop pp=de/lb/-al).

MB>command line even using the lb filter?

No.

Look for mplayer output - it should write something like

Opening video filter: [pp=de/lb]
[vo] query(Planar YV12) -> 1
[vo] query(Planar I420) -> 1
[vo] query(Planar IYUV) -> 1
(no errors)
(some unrelated messages)
[PP] Using external postprocessing filter, max q = 6
(messages)

if you make an error, it writes

Opening video filter: [pp=de/slb]
[vo] query(Planar YV12) -> 1
[vo] query(Planar I420) -> 1
[vo] query(Planar IYUV) -> 1
1 errors in postprocess string "de/slb"
Couldn't open video filter 'pp'
(no more pp-realated messages)

pp='lb/ ' is incorrect syntax. So, don't make any errors!
You can find something about pp syntax by running
mplayer -vop pp=help some-file
