Regarding Carl's suggestion, can you tune in digital stations while the
amp and splitter are in place? If so, it probably isn't a signal
strength issue. <br><br><div><span class="gmail_quote">On 10/12/05, <b class="gmail_sendername">Chris Ribe</b> <<a href="mailto:chrisribe@gmail.com">chrisribe@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
FWIW, Comcast uses splitters that are only rated to 900Mhz or 1.2GHz when they do installations. <br>
<br>
I've encountered similar problems doing installs for people, but
unfortunately I don't know what the solution is (one time it turned out
that the problem was a temporary and neighborhood wide, but it just
happened to commence while I was punching down the distribution block
in someones basement). I've heard that Comcast will provide an
amplifier if one is necesary. <br><br><div><span class="q"><span class="gmail_quote">On 10/12/05, <b class="gmail_sendername">jesse k</b> <<a href="mailto:kirchner@alum.mit.edu" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

I have a MythTV/Gentoo box which is working very nicely. I've managed<br>to enable all the functionality I want other than getting premium<br>channels to work (the various HBOs). This is fine with me as On Demand<br>obviates the need to record those shows. However, the hardware I've
<br>used to split and amplify my cable signal seems to interfere with the<br>On Demand service.<br><br>The setup (<a href="http://jessekirchner.com/file/cable_setup.txt" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://jessekirchner.com/file/cable_setup.txt</a>) I have is as
<br>follows. I use a Radio Shack 16-2568 2-way splitter (40-2150MHz) to<br>divide the incoming co-ax cable signal. One line goes to the<br>WinTV-PVR350 card in my MythTV box from which I deliver the signal<br>over S-Video to my television. Due to signal degradation from the
<br>splitter, I use a Radio Shack 15-1170 inline powered amplifier<br>(50-2200MHz) to boost the strength before the Motorola DCT2000 series<br>set-top box. The signal is carried by co-ax from the set-top box to<br>the television.
<br><br>I cannot use On Demand with the above-described setup. When I want to<br>catch up on Rome or Six Feet Under (RIP), I need to unhook the input<br>line from the splitter and feed it directly into the set-top box<br>
during which time, my MythTV box cannot record with a live signal<br>(however, it will dutifully record hours of static). I've tried to no<br>avail removing the amplifier to see if that is blocking the On Demand<br>signal. This leads me to suspect that the frequency pass on the
<br>splitter (40-2150MHz) is too narrow. (And yes, I realize that the<br>amplifier frequency pass is almost identical, but I dont have the<br>hardware to check that individually and I want to take this one thing<br>at a time.)
<br><br>I'd like to find a splitter that will allow the necessary frequencies<br>through, but I have no idea where to start. Before I bug Comcast (I<br>don't have much faith in their ability to help with non-standard<br>
questions), I want to see if anyone in this forum has encountered a
<br>similar difficulty or might know a good place to post this query.<br>Also, if I seem to have a lapse in understanding, please feel free to<br>school me.<br>--<br>Jesse Kirchner<br><a href="mailto:kirchner@alum.mit.edu" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
