Using lavc is highly recommended. Currently there is no way of setting the
fps of the em8300 which means that it is fixed to 29.97fps. Because of this
it is highly recommended that you use <CODE>-vop lavc=&lt;quality&gt;:29.97</CODE>,
especially if you are using prebuffering.</DD>
it is highly recommended that you use <CODE>-vop lavc=&lt;quality&gt;:25</CODE>,
especially if you are using prebuffering. Then why 25 and not 29.97? Well,
the thing is that when you use 29.97 the picture becomes a bit jumpy. The
reason for this is unknown to us. If you set it to somewhere between 25 and
27 the picture becomes stable. For now all we can do is accept this for a
fact.</DD>

<H4>MPEG1, MPEG2, VCD and DVD Notes</H4>
<P>MPEG1/2 content should now automatically be detected by MPlayer and
it will use the hardware acceleration of the DXR3 to play it. If not, you can
force it to hardware acceleration with <CODE>-vc mpegpes</CODE>. Also, if you
plan to use postprocessing filters you must use <CODE>-vc mpeg12</CODE>.</P>
<P>In some instances, subtitles may not appear properly in sync with the A/V
stream when using hardware decoding (<CODE>-vc mpegpes</CODE>). This is a
known bug. The em8300 will also improperly handle subtitles that are too big,
and may hang for a second or two. At this time, the only workaround is to use
<CODE>-vc mpeg12</CODE> when viewing DVDs with subtitles. When running with
<CODE>-vc mpeg12</CODE> MPlayer will reencode video to MPEG (even if it
already is MPEG). This means that it will need more CPU power, and you might
loose some picture quality.</P>
