<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> I’ve
noticed a quirk in untranscoded HDTV video (MPEG2 from an pcHDTV 3000 card)
that I haven’t found a solution. Whenever I play 1080i content and
try to use the time stretch feature, nothing happens. The video stays at
1X. Coincidentally, the audio gets choppy as I adjust the Time Stretch
(but doesn’t change speed). As I increase the speed, the amount of
audio choppiness also increases. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> I
am using XvMC through an Nvidia 5200 FX card, have a 2.8 GHZ HT Pentium 4, and am
outputting sound to an external amplifier via an optical out. During the time-shift
and without it, the CPU is reasonably low and does not change between the two.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> The
crazy thing about this is that if I try to time shift untranscoded video from
the same card at a lower resolution, the timeshifting and the audio is perfect.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> I
suppose this could be a weird XVMC quirk (I noticed that the chroma hack doesn’t
work for me… still have the black and white OSD), but not really sure where
to start if it is.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> Anyone
experience anything similar or have any suggestions for this?<o:p></o:p></span></font></p>
