Watching recorded TV
Freevo comes with defaults that will work for many users who have followed the configuration wiki. Specific problems that you may encounter are Output to a TV, and deinterlacing problems. If you are recording using a hardware Mpeg2 encoder, or creating interlaced recording files, you may experience interlace problems. It requires processing to deinterlace; you are far more likely to obtain good results if you are using a good overlay filter. Some examples are: xv, which is the easiest to configure with good results, x11, which provides no accelleration and therefore can be a problem with deinterlacing, and gl, which can provide good results but is difficult to configure. The video overlay allows your graphics card to do some of the work of image processing, particularly deinterlacing.
Deinterlacing in Mplayer
There are a number of deinterlacing options in mplayer. Many are very poor; see This article on deinterlacing filters for details. An acceptable setting for most purposes is cubic interpolation:
MPLAYER_VF_INTERLACED = 'pp=ci'
This is also an equally good setting for converting such files to avi using mencoder. If you find that sometimes freevo autodetects interlacing incorrectly, you can also set
MPLAYER_VF_PROGRESSIVE = 'pp=ci'
However, this should not be necessary if everything else is set up correctly. Cubic interpolation like this consumes 20-30% of the processor time on an Athlon 2500+.
