</div>Sorry, that was a pretty lame description. I am using component cables<br>
and optical SPDIF to record 720p cable from an SA3250HD.<br>
<br>
Per the other response in this thread, I read this thread:<br>
<div class="im"><a href="http://www.gossamer-threads.com/lists/mythtv/users/409442" target="_blank">http://www.gossamer-threads.com/lists/mythtv/users/409442</a><br>
<br>
</div>It looks like I'm now in that same boat. I am wondering whether anyone<br>
nailed the problem down. It looks like a couple leading theories<br>
centered around dirty AC3 from the source and/or flaky USB<br>
controllers. I am actually using three USB hard drives in addition to<br>
the HD-PVR and am really hoping that's not the problem. I can switch<br>
to stereo for testing purposes though, if people are still thinking<br>
that's the culprit.<br><br></blockquote><div><br></div><div>So far, no dropouts using RCA stereo cables. I guess the AC3 was the problem. I suppose I could try a better cable?</div></div><br>
