<div>What I have found is that several others have had this
problem and have isolated it to VDPAU with an interlaced
source. We had a lock up again last night and sure enough
the source was 1080i and the output is 1080p.</div>

<p>I have found that using High Quality software decoding to be
more reliable and tolerates faults in the broadcast stream. The
cpu load is only moderate - try it.<br>
</p>
<p>By the way this issue is still present in V31 so upgrading will
not help.</p></div></div></blockquote><div><br></div><div>Thanks so much for the confirmation of the issue. I have been wondering about using software but wasn't sure my CPU could handle it. What specific settings do you recommend?</div><div><br></div><div>Allen </div></div></div>
