Have you tried using the -s option on the channel changing script? That did the trick for me.<br><br><div><span class="gmail_quote">On 10/4/07, <b class="gmail_sendername">Daniel Arfsten</b> <<a href="mailto:darfsten@hotmail.com">

<br>have my sa3250hd NOT accepting the tune command of the sa3250ch channel<br>changing script either. I have been unsuccessful for over 40 hours of<br>testing and playing around and googling, ensuring I was using the latest
<br>test-mpeg2 and firewire_tester, and sa3250ch channel changing script to no<br>avail. My vendor code is in there and it appears to work but it just doesn't<br>work! Here's my thread.<br><a href="http://www.gossamer-threads.com/lists/mythtv/users/290860?#290860">
http://www.gossamer-threads.com/lists/mythtv/users/290860?#290860</a><br>Maybe you can point out anything that I may be doing wrong?? I should just<br>call them and make sure the "tune" functionality is "enabled" on my boxes. I
<br>did specifically tell them that I needed the ports enabled for using it with<br>my TIVO, just because I didn't want to haev to explain mythtv. What's weird<br>is that I can capture my local stations with test-mpeg2 but no channel
<br>changing no matter what I do????? I don't even really care about being able<br>to capture stuff, I just want to use s-video out on the cable box and use<br>firewire to set the channel for mythtv to record but it's not working.

<br>as described<br>in the non-freely available CEA-931-A spec. I am willing to<br>purchase<br>CEA-931-B (which superseded CEA-931-A) in order to try to go<br>further.<br><br>I can't believe that I'm the first person to work though this
<br>(I'm not that<br>original ;) ). Does anyone already have this spec? I am aware<br>that the spec<br>is copyrighted, and I'm not looking for a free copy, but does<br>that prevent<br>implementing it? What am I missing?
