<BR>
</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>
<BR>
I've been using my hd-pvr with AC3 over S/PDIFF without dropouts all along. Bog standard USB cable over cheap, builtin mobo controller. Would tend to support the source theory??<BR>
<BR>
My decoder is a Motorola IP-STP 1700 (or something like that - ethernet signal, no builtin harddisk). The only time I have problems (sometimes) is if I change channel during a recording.<BR>
<BR>
Cheers!<BR>
