<p class="MsoNormal">I am having a problem with 720p video when using
mplayer
(Debian Sid MythTV 32--bit and nVidia 9500GT). The video will play for
about
30s – 60s and pause slightly for a second or two. The process then
repeats.
However when using the Internal Player there is no stutter whatsoever.
Strangely
on my Debian Sid MythTV 64-bit and nVidia 8300; mplayer has no issues.
Both
systems are kept update at the same time.</p>
