[MPlayer-users] Re: best encoder ?

[Martin Hoffmann]

I guess you should add "-vop pp" and "-npp lb" to deinterlace the source - 
since a lot VDR recordings are interlaced !
Otherwise you will get a lot of interlacing stripes !

btw: When using XVID with interlacing turned on, you do not need to 
deinterlace an the picture will look more sharp (no motion blurring) - 
However if you do not intend to playback on tv set then deinterlacing is the 
best method !

@Karsten Müller: You can also get my vdr2divx scripts for automatic conversion 
at http://ma.hoff.bei.t-online.de/2divx/ - 1.53 is the latest - new one will 
follow !

Martin.
