Has anyone had any luck with getting this STB to recognize channel change commands?<br><br>I've tried the firewire_changer code that Jim provided, and I'm getting exactly the same results that Brian got; failure on the individual buttons, and reported (but not actual) success on the the tune method.
<br><br>I've modified the sa3250ch code to allow me to send hex commands to the STB and have been using the (admittedly old, but freely available) AVC 3.0 spec (<a href="http://http://pbx.mine.nu/dvhs/AVC_30.pdf" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://pbx.mine.nu/dvhs/AVC_30.pdf</a>), the avc1394.h file, and various web pages as guides.<br><br>I've been tinkering away at this for the last week, and so far the only thing that has worked is detecting the current power state of the STB:
<br><br>When power is off (via the power button on the STB):<br>AV/C Command: cmd0=0x01ffb27f cmd1=0x00000000<br>Response: 0x0CFFB260 cmd1=0x00000000<br><b><span style="font-weight: bold;">

<a href="http://http//hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-225A1.pdf">http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-225A1.pdf</a>) which requires STB's to support the pass through tune command as described in the non-freely available CEA-931-A spec. I am willing to purchase CEA-931-B (which superseded CEA-931-A) in order to try to go further.
<br><br>I can't believe that I'm the first person to work though this (I'm not that original ;) ). Does anyone already have this spec? I am aware that the spec is copyrighted, and I'm not looking for a free copy, but does that prevent implementing it? What am I missing?
