I joined the mplayer mailing list and have tried to seek help/information from those nice folks..&nbsp; The following is part of one of my exchanges.&nbsp; Maybe the part about the timestamp may be of some help?<br><br><span class="q">
&gt; I asked a couple specific questions and included some quotes from other<br>&gt; posts to provide an idea of what we're looking at as the cause. &nbsp;I can't<br>&gt; tell you what the exact problem is because we're still trying to figure that
<br>&gt; out... &nbsp;And a good place to start is by comparing the differences between<br>&gt; the software that has the problem and software that doesn't. &nbsp;We're<br>&gt; trying to figure out what mplayer does, if anything, with regards to
<br>&gt; repacking, the pes layer, pcr data, etc. during the &quot;playback&quot; of a VDR &quot;recording&quot;.<br><br></span><div style="direction: ltr;">nothing particular: the pes packetization is as standard as you can get,
<br>except that IIRC there's a timestamp on every single frame,<br>rather than once every 0.5-0.7 seconds; this fact alone can make a<br>lot of difference during playback.<br>Does the desync that you are experiencing get worse with time or does
<br>it regularly decrease and next increase?</div><br>
