</div>It is worth trying all options from 1 to 7. Even though it looks like<br>
each encoding is for a different box, the reality is that these are all<br>
permutations allowed within the standard. If none of these work then<br>
there is a permutation missing.<br>
<br>
What mythchanger does is use the PANEL commands for an STB. This in<br>
effect is like pressing the buttons on a remote or front panel of the<br>
STB. Sometimes you can send the digits in a block (usually optional) but<br>
sometimes they have to be sent button by button. Sometimes the STB is<br>
looking for key press down and in others key press release. And in some<br>
cases like some SA boxes it is looking for a key press down followed by<br>
a key press release. The sequence of buttons required to change the<br>
channel should be the as on your remote. So if you need to press enter<br>
at the end then you will also need to do this via firewire (say using<br>
stb-command). The protocol for this has not been more complicated than<br>
this in my experience.<br>
<br>
You can play with the code and try different options based on the<br>
examples you see. The first thing to note is try any digits with various<br>
options and see if the STB is responding at all.<br></blockquote><div><br>So what does it mean if I've tried all 7 permutations, each with combinations of 1, 2, 3, and 4-digit channel numbers, and in every case, the STB does not respond in any way whatsoever? And I'll add that *capture* over the exact same firewire connection works perfectly, as long as I manually set the channel using the remote.<br>
